not sure I understand this code.

This code ends up in latex.ltx and that has a very well defined format 
date, so at that point the \fmtversion will *always* be, say 2021/05  or 
later

So unless I'm totally misunderstanding something this code will never 
branch (latexrelease changing \fmversion will come later not while 
latex.ltx is processed). Something wrong with this reasoning?
