I installed my latest server without lib32 and haven't hit any problems.
I know that Wine used to (and maybe still does) need 32 bit libraries.
There are also 56 ports that are flagged as for i386 but not amd64, but
for the great majority of things I don't think you need lib32.

It would be helpful if a core developer could say what the official
policy is.
