For my part, I am very much cognizant that I have written maintainer scripts
that do not smoothly support downgrades -- because it would have been
significant extra effort to get it right, and downgrades are not supported.

(Well, there was that one NMU of libapache2-mod-perl2 which supports
downgrading, but that fell out as a freebie when implementing proper support
for all the documented maintainer script use cases in the policy manual. ;)
