This is perfect and clear behavior, actually:
$ FUNCNEST=10; foo() { foo; }; foo
bash: foo: maximum function nesting level exceeded (10)
If bash were to set a default value for FUNCNEST then a useful error
would be provided rather than segfaulting (and possibly triggering a
coredump). Of course, if bash itself is sharing a stack with the
interpreter, then it's hard to come up with a good predetermined value.
FUNCNEST doesn't seem to work with the issue of recursive traps, though
(understandably).
