I guess there's little point to be too ambitious here, given that 
vc-transfer-file is not interactive, and changing vc-next-action's 
signature is not in the cards now anyway.

And we don't have an actual mechanism for obsoleting only a part of 
command's calling convention.

I have pushed the change which obsoletes vc-switch-backend now.

Which should remove the main obstacle to adding the branches map with 
good binding in Emacs 29.
