Can I remove composer.json?

[Vigilante]

Just a noob question here. I installed a fresh copy of PW and getting started on a new site. I was just wondering if composer.json (Composer in general) is necessary for PW to function.

If I don't intend to use Composer with the site, is this still required? The default composer file doesn't really do anything except require ext-gd and point to the autoload file. But if I don't run Composer commands, it's not installed on my host, then why have it?

I didn't see in the install docs whether this is needed or not, so I'd rather just delete the json file if unused and keep my file system clean.

You don't have to delete it, but if you're not using composer, there's no reason to keep it.
