As I understood it, lastlog never really grew in size because
there is only 1 entry for each user on your system, and when
the logged in, that entry was updated. I also though on some
systems, this was a sparse file where the index of your entry
was based on the uid. How it is in FreeBSD may not be the
same, in that I have not looked into it.
