Yay! I see several good things that could come out of this, but to prevent pitchforks and misunderstandings, I think this RFC should be split some more.
So ideally, this should be split into multiple RFCs. The ones I can think of, so far:
1. LESS support for RL. 2. Separate CSS(LESS?) that applies just to content, and is scoped as such. 3. An easier way to custom-style your wiki that does not require you to edit CSS, and also can be as flexible as the current one. 4. Remove customizability via Site / User CSS.
1 and 2 should mostly get general support, and *should* get what we want (content styles that we can load by themselves without conflicting the UI). 3 is awesome, but also very hard - and does not have a clear use case. 4 is akin to taking away internet from a hackerspace and is a lot, lot harder - and of limited benefit.
So... split this? :)
