GNU libc 2.38 now has strlcat and strlcpy wrappers

and

https://sourceware.org/git/?p=glibc.git;a=commit;h=454a20c8756c9c1d55419153255fc7692b3d2199

(they are also present in musl see
https://elixir.bootlin.com/musl/latest/source/src/string/strlcat.c
and

The only tests that we have at the moment in memcheck are for strlcpy on Solaris.
