Yes, but all the user would have to do is change a few characters in the name. If we don't go by this rule people could name their ExGFX files as, for example, "Hahaha this is a huge file name [BG1].bin", which certainly takes more effort to rename.
Edit: also, it makes our job as Graphics Moderators faster, since we can readily insert those graphics and test the sample level.
