for people from languages that mark gender with an ending (romance languages for instance), putting the "wrong" ending something like a noun would sound odd or change the meaning

I feel like when I was a child more people were present with a PH, but nowadas virtually nobody. Most of the Stephens I know are "old", and I think "Steve" won.

But no doubt it varies on country, and who you know.

(I legally changed my name from Steven to Steve, a couple of years ago, because it was the only name I'd ever used and it got too tiresome dealing with my official passport, and ID saying one name when I signed/wrote another name on all my official paperwork. To the extent that employers would book flights in one name but my passport was in the other name, cue much hilarity at boarding time..)
