In their shul they make the rules. Theycould be makpid that only people with names starting with w can daven for the amud or that only a certain nusach can be davened.
In most shuls its safe to assume that outside of the main beis medrash they dont mind if ou daven another nusach or if a non-w name davens. (I wouldnt assume this for certain kehillos identified in the previous question)
So to answer your question “”do I even have to worry about it?”
unlike the starting letter of the person davening which I doubt anybody cares about, there are definitely some shuls that are makpid on this. Best is to ask.
