Wikia has a huge number of features and limited resources, so we have to pick our battles. We do recognise the problem though, and it's something we've been actively discussing - sometimes the best solution is simply to retire a feature that isn't working out, so we can focus our efforts. Special:CSS is another example of this - trying to support two different advanced code editors was wasteful. Better to take the hard decision to retire one and focus our resources on making the other better.
