If the facility is later implemented as a C executable (or whatever)
instead of a shell lib, the shell lib would still have to be shipped in dpkg
so that maintainer scripts don't fail ungracefully when trying to source it.
That makes it hard to ever get rid of that interface once deployed.

No, the way to get dpkg upgraded first is by declaring the Pre-Dependency on
dpkg.  Then, if there *is* a pre-dependency loop, it's detectable and should
be resolved...
