In my mind and from the requirements from the transition plan the idea
would be to make the new dpkg install-info version mostly a no-op and
just warn, that should be fine because as long as no info-browser is
installed it should not matter if the dir file is not up-to-date. This
also avoids breaking all packages that unconditionally call install-info.
But the Replacing install-info from the new install-info package would
work normally, so that stuff like “make install” from local sources
would work. The only minor issue is that for awhile we'll get duped
work done by the maintainer scripts calling it and the triggers
regenerating the dir file. A solution for that could be to make
install-info do nothing if called from inside a maintainer script by
checking for the DPKG_RUNNING_VERSION environment variable for example
(this can go once the wraper in install-info disappears).
Hope this clarified.

Sure, that's up to you.
