You can test by debootstraping a pureos chroot and then install the
unpatched cron and compare package lists before and after.

AFAIK there's no mta installed on PureoS Laptops at all and having it as
'Recommends:' would pull in a mta by default (since Recommends are
installed by apt if not told otherwise).
