Yup it's safe to remove 'cryptsetup-run'.  cryptsetup <2:2.0.3-1's
(≤Stretch) functionalities have been subsumed by the combination of
cryptsetup-run and cryptsetup-initramfs between 2:2.0.3-1 and 2:2.0.3-5
(Buster); and the combination of cryptsetup-run and cryptsetup-initramfs
since 2:2.0.3-6 (≥Bullseye).

I'm about to upload 2:2.0.3-6 where:

  * cryptsetup-run is a transitional depending on cryptsetup (like for
    2:2.0.3-5); and
  * cryptsetup is a “real” (non-dummy) package recommending
    cryptsetup-run.

That seems to be enough to avoid triggering cryptsetup-run.prerm with
action “remove” upon `apt upgrade --autoremove`, and that also on
systems where APT::Install-Recommends is set to ‘no’.

The package can be safely removed later, for instance with `deborphan
--guess-dummy`.  Once Bullseye is released we'll be able to remove the
‘Recommends: cryptsetup-run’, or even cryptsetup-run altogether.

Cheers,
