LLD hasn't been extensively tested in the wild (before FreeBSD). Newer may need
less LLD_UNSAFE. Explicitly rejecting -z <unknown> is better than silently
accepting it to prevent runtime bugs.

Users don't usually install from /release_<n> but /quarterly. The latter is a
moving target. By the time 12.0-RELEASE more ports can be fixed.

How many ports builds shouldn't be very important from base system POV. The
primary concern is catching toolchain bugs (e.g., bug 230622 or bug 230412), so
consumers (not just ports) don't have to invent gross workarounds. Obviously,
too few ports building would prevent enough exposure. However, if you need a
stable compiler stick to a specific devel/llvm* on all FreeBSD versions. Why
FreeBSD release engineering is still driven by ports/ freezes, something which
was abolished years ago?
