You could only do this if you wrap the choice in variants. Automatic
detection does not work with binary archives. Everything influencing the
build must be defined by the canonical combination of
name/epoch/version/revision/variants for reproducible builds.

And even if the default +db* variant selection depends on the local
active db* version, I guess such a change would trigger more local
builds instead of using binary archives which should be preferred for
most users.
