No, as I mentioned elsewhere, the NetBSD iimplementation does not allow 
strlcpy(0, SRC, 0) whereas the FreeBSD implementation does (and this 
disagrees with the FreeBSD documentation where it says the destination 
must be a string).  I haven't investigated strlcpy but I expect that it 
differs too.

It is a bit of a mess.

It's certainly OK to reach out to the OpenBSD and FreeBSD and NetBSD 
folks here, in particular as to whether applications rely on these weird 
corner cases. I am pretty sure they do not, and that it'd be better to 
make them errors.
