FWIW, very few things in contrib use anything beyond libc. The dblink stuff
is a notable exception. It needs an SSL and a Kerberos 5 library.

If the library is reasonably popular (meaning it's in at least one major OS
distribution, including Debian) then 'what's the harm?' If the lib isn't
that popular, then, regardless of license the question 'should something that
uses it even be here' should be asked. The issue of a straight GPL library
is serious for us; a LGPL one less so.
