How do I delete a repeater field via API

[hellomoto]

I have a module that creates a repeater field on install:

        $f = new Field();
        $f->type = wire('modules')->get('FieldtypeFieldsetTabOpen');
        $f->set("name", "iu_maptab")->set("label", "Mapping");
        $f->set("tags", "impupd")->save();
        $r = new Field(); $rName = "iu_map";
        $r->type = wire('modules')->get('FieldtypeRepeater');
        $r->set("name", $rName)->set("label", "Map Fields");
        $r->set("tags", "impupd")->save();
        $f = new Field();
        $f->type = wire('modules')->get('FieldtypeSelectExtOption');
        $f->set("name", "iu_field")->set("label", "Template Field");
        $f->option_table = "fields";
        $f->option_value = "id"; $f->option_label = "name";
        $f->set("tags", "impupd")->set("columnWidth",50)->save();
        $f = new Field();
        $f->type = wire('modules')->get('FieldtypeText');
        $f->set("name", "iu_value")->set("label", "Source Value Selector");
        $f->set("tags", "impupd")->set("columnWidth",50)->save();
        $f = new Field();
        $f->type = wire('modules')->get('FieldtypeCheckbox');
        $f->set("name", "iu_static")->set("label", "Use Static Value");
        $f->set("tags", "impupd")->set("columnWidth",50)->save();
        $f = new Field();
        $f->type = wire('modules')->get('FieldtypeFieldsetClose');
        $f->set("name", "iu_maptab_close");//->set("label", "Mapping");
        $f->set("tags", "impupd")->save();
        $rfg = new Fieldgroup();
        $rfg->name = "repeater_{$rName}";
        $rFields = ["iu_field", "iu_value", "iu_static"];
        foreach($rFields as $rf) {
          $rfg->append($this->fields->get($rf));
        }
        $rfg->save();
    		$rt = new Template();
    		$rt->name = "repeater_$rName";
    		$rt->flags = 8;
    		$rt->noChildren = 1;
    		$rt->noParents = 1;
    		$rt->noGlobal = 1;
    		$rt->slashUrls = 1;
    		$rt->fieldgroup = $rfg;
        $rt->save();
        $rpg = "for-field-{$r->id}";
		    $r->parent_id = $this->pages->get("name=$rpg")->id;
		    $r->template_id = $rt->id;
		    $r->repeaterReadyItems = 3;
        foreach($rfields as $rf) {
          $r->repeaterFields = $this->fields->get($rf);
        }
        $r->save();

Now I can't uninstall it, on account of a field being used in the fieldgroup created for the repeater -- can't delete that field because it's in the fieldgroup which I am trying and failing to delete:

        $rf = wire('fields')->get('iu_map');
        $rt = wire('templates')->get('repeater_iu_map');
        $rfg = $rt->fieldgroup;
        if($rf) {
          wire('fields')->delete($rf);
          wire('fieldgroups')->delete($rfg);
          wire('templates')->delete($rt);
        }
        foreach(wire('fields')->find("tags*=impupd") as $f) {
          wire('fields')->delete($f);
        }

ProcessModule: Unable to delete field 'iu_field' because it is in use by these fieldgroups: 'repeater_iu_map'

Please help this is such a bother. The fieldgroup should be deleted before attempting to delete the field itself.

Can I delete this somehow I got it with just

        $rfg = wire('fieldgroups')->get('repeater_iu_map');
        wire('fieldgroups')->delete($rfg);

though I could swear I'd tried that and so much more

System fields and templates cannot be deleted without first removing the 'system flag'. Example code:

$t = $this->wire('templates')->get('your-template');
if ($t->id) {

    // two step process to delete system template
    if ($t->flags == 8) {
         $t->flags = Template::flagSystemOverride;
         $t->flags = 0;
         $this->wire('templates')->delete($t);
         // delete the associated fieldgroups
         $this->wire('fieldgroups')->delete($t->fieldgroup);
    }

}
