Only a problem if someone decides to make things that aren't meant to be moddable preemptively moddable.

Modifiability:
GUI pages should be modifyable, even if its just for allowing them to change strings, colors or styles.
The GUI pages were modifyable already.
Noone added a hint that the page should be non-modifyable.
If mods want to change some color or label, they will find a hacky or non-hacky way to do so.

Readability:
Making it an exercise to the reader to figure out which files are used by which page wastes the readers time.
Minimizing the number of files to iterate when using grep or sed reduces the maintenance time.

Assuming that people would either use common sense to figure out if something is a good idea instead of having a single tool and applying that to everything, or people asking in case they aren't sure or want details was apparently a bad assumption. Then again feel free to fuck this up once I'm done with this.

If people want to do something stupid to something sane I'm not going to help them do that. But as said, you can break this once I'm done with it all you want.

Ah, that reminds me that I should probably rename some functions to mess up any code that includes everything for the sake of doing so.

But then it would have to be placed, and whatnot. The gui is the PoC part ;-)
