From 2013-02-17 02:54 until today its size became 13.7 MB on my install.
I "collect" all local build packages in three cache directories,
current/, old/ and very_old/. At the moment I don't feel the need to
delete anything. In case of emergency I would delete the very old
packages, not a small log file.
FWIW I regularly run 'pacman -Sc'.
I could imagine to 'mv' /var/log/pacman.log to
/var/log/pacman.log-2020... if there should be the need to get rid of
clutter, such as output of pacman typos, if it one day should become
annoying to use search with 'grep'. However, since the file is that
small and the complete history could become important, I don't remove it.
