That's pretty much how it is now. The only problem with it, is when people want to abbreviate, since both RP-Enforced and RP-Encouraged abbreviate to RPE. As for the whole "well if RPI people wanted their games to be exclusive, they should've made a better abbreviation when they created it" - at the time, they were the ONLY ones who wanted to call themselves RPIs, and so they did, and it stuck, and everyone who knew about the existence of any differences in the first place, knew what everyone meant when they used the term RPI. It was only after the fact that some games chose to call themselves RPIs, when they weren't like the games that had already been calling themselves RPIs, and everyone who knew about them recognized what that meant.

Sort of like criticizing people who call windows "windows" - just because windows is now the latest trendy word to describe a wall-hanging picture frame. Sure, you can call it a window. But it won't be that glass partition between the inside of your room and the back yard.

And sure, you can call your hack-n-slash mechanics game with 400 socials (or verbs, if you prefer), and levels and exp points that requires you to be in-character all the time an RPI, but it still won't be an RPI.
