But when and unless aren't functions, they are "special forms".  So
using &rest there is less self-explanatory for those who aren't
necessarily privy to the internals.

IOW, the removed (fn ..." stuff was there for a reason.  The original
bug report here wasn't about how we display the doc string, it was
about what eldoc does.  So IMO the fix should have been in eldoc,
which would also avoid this negative effect.
