They shouldn't be accepted at the declaration site. Default arguments for
function pointers and delegates make no sense. The only time that default
function arguments are used is when you call a function by its name and you
don't give all of the arguments, in which case the default arguments are
effectively copy-pasted at the call site. As function pointers and delegates
aren't named (variables referring to them may be, but they themselves aren't),
and default arguments aren't part of a function's type, there's no way to call
them with default arguments without the compiler special casing situations like
the one that you give here.

Now, even given all of that, I don't think that this is a regression. The fact
that it complains at the call site and didn't before is a bug fix, not a bug.
And it's never complained at the declaration site, so not complaining is
exactly what it's been doing, so it can't be a regression even though it's a
bug.
