Good point, you are right. :-(
Then we are up to plan B, which is a bit more complex but should still 
be approachable:

  Another option might be to have the new libc6 Conflict with old versions
  of Essential:yes packages that need libcrypt1, forcing those Essential:yes
  packages to get upgraded first. A quick check based on libcrypt1 reverse
  dependencies in sid shows perl-base, login and util-linux. I'm not sure
  if this list is exhaustive, though.
