It is your task to show that Debian is affected.  I have never seen
this problem at all and I would assume a lot more bug reports if this
would be show up more often.

No, dmsetup is _not_ required, it never was:

| Package: dmsetup
| Source: lvm2 (2.02.111-2.2)
| Section: admin
| Priority: optional

You mean dmsetup is required in Ubuntu?  Then you may have found your
problem.  apt have some special handling of required and/or essential
packages.
