A typical objection against V=L is that it restricts
the multitude of sets.
If one draws a parallel with standard/nonstandard
mathematics, then the same argument will work against
the "standard" model of PA and in favour of a suitable
choice of a nonstandard model
(say, recursively saturated) as the base for arithmetic,
which indeed does not happen.
Still there is an interesting fom-like question related
to V=L:
QUESTION: is there any mathematically meaningful statement
about projective sets
(in particular different from consistency of something)
which V=L does not decide ?
