Is it ok to use MarkupRegions on one template only?

[JayGee]

Just checking something I've not done before...

I've upgraded an old site to PW latest stable and I want to add some new features using MarkupRegions but only on one template.

I've enabled MarkupRegions in config as usual but skipped the append. I've then appended my _main.php file in the template settings instead, so as to target it only to one template type in the site.

$config->useMarkupRegions = true;
//$config->appendTemplateFile = '_main.php'; <--- added this manually to one template in the UI instead of via config.php

Is this ok? It seems to be working, but just checking I'm not introducing any unforeseen pain? I've only ever used MarkupRegions as an all-of-nothing type thing before!

Uneducated guess: I think it should be fine.

12hrs later I can confirm everything is running smoothly so far! Will report back on this thread if any issues. But great to know we can use MarkupRegions retrospectively on older sites like this.
