Visisbility define use is a nice theory but in practice it's a mess.

Probably, before hiding, someone(tm) should build a system with them
hidden and do a bulk build.

More seriously, NetBSD having breaking changes generally does not go
well, unless Linux has had the change for a year, so that upstreams have
had time to adapt.
