Lua is more powerful, yes, but ParserFunctions are similarly difficult at times. The sheer amount of { and } is enough to confuse anyone even experienced editors. PF is an extension however, it's not a feature of core (the same as Scribunto) so it's not a case of deprecating one in favour of the other. I imagine there might be cases when there's methods in PF that are available in Scribunto in much the same was StringFunctions was merged into PF, but I can't see a direct replacement ever happening.
