Difficulties using parser functions are exactly because wikitext is ill-suited for them. It was simply a way to make pages more manageable. Although people overused it and now many templates are a mess, and it is particularly hard to change a bad habit.

This is why I believe it should simply be disabled, there is no way of correcting this behaviour because unlike a programming language there is no parser to force people to use it properly. You can even leave a page full of erronous calls to parser functions with no problems.

The issue is that even in well-established and popular wikis, they simplyignore the errors caused by parser functions. Porting useful parserfunctions to lua makes much more sense, and will help reduce bad "wikitext coding" practices.

So really, I don't see any advantage of keeping it save for catering to diehard parserfunction fans.
