I doubt this will be an issue. zlib is installed by default on
pretty much all Linux distributions as almost everything uses it one
way or another.

Most Samba packages will have an explicit zlib dependency already if
they want to avoid linking in the bundled version of zlib.

It will be more of an issue for those wanting to run Samba AD or
OpenChange on non-Linux/BSD platforms without a proper package manager.
