Only with enabled discard option in /etc/crypttab, because trimming of
LUKS significantly decrease security level (everyone even without
password/key knowledge can identify that drive contains LUKS filesystem
and used disk space).
That's already a default in Fedora, as we've already made that trade-off. This
is why I personally wouldn't use TRIM, but I can certainly see how it'd be
useful to those who are actually looking for longevity (not performance, TRIM
doesn't get you better performance) over security.
