"The Debian Way" as far as packages are concerned. The administrator
can do anything she pleases. It's far safer for automated scripts to
create/remove files (in /etc/cron.{d,daily,weekly,monthly} in this case)
rather than add or delete lines from a file (/etc/crontab).

*sigh*
man cron(8):
DEBIAN SPECIFIC
cron treats the files in /etc/cron.d as extensions to the
/etc/crontab file (they follow the special format of that
file, i.e. they include the user field). The intended pur
pose of this feature is to allow packages that require
finer control of their scheduling than the
/etc/cron.{daily,weekly,monthly} directories allow to add
a crontab file to /etc/cron.d. Such files should be named
after the package that supplies them. Files must conform
to the same naming convention as used by run-parts(8):
they must consist solely of upper- and lower-case letters,
digits, underscores, and hyphens. Like /etc/crontab, the
files in the /etc/cron.d directory are monitored for
changes.
