Very interesting.

Have you considered using debhelper substvars for this?  Like how we
have ${elpa:Depends}.  It avoids needing a control.in.  A control.in
isn't the end of the world but it might be cleaner not to have one.

Don't sharpquote lambdas; unlike in CL, doing so will mean they don't
get compiled (I think).

You can rewrite the cond using cl-case or pcase.

Use cl-incf (just incf in Emacs 31) instead of setq and 1+.

I see you're using package--builtin-versions.  I'm not happy to be using
an internal variable -- it got us in trouble before!
