To me, the OPs suggestion has a point. So far, there are many MSL identifiers, switches and properties that serve convenience only - I can think of several situations where this one could be of use. Though, like Riamus2, I don't think it's a "high priority" thingie.
Given that the case may already be solved with $findtok($match/wildtok()) and the OP is looking for a cleaner/shorter implementation only (which might well increase performance), a regsubex looks ludicrous in terms of readability, script size and performance.
Why do you assume he wants to $gettok thereafter? He is using $findtok for the very end of finding not the token itslf, but its position in the string. Maybe he needs the value itself, or wants to $instok after the match, or $reptok/$remtok a $wildtok match, or what have you...
