I think the above aptitude searches do not list such packages because
the ~A string is empty for their installed version, which is no longer
in experimental.

I use

  aptitude search '~S~i!~Ae'

to find all my outdated packages that came from experimental. This will
also list the obsolete (~o) packages and it relies on the fact that all
archive names from stable to experimental contain at least one "e". You
can combine this with '!~o' to exclude the "standard" obsolete packages;
I use the above search string as a display limit in interactive mode,
where these two types of packages are listed in different categories
anyway ("upgradable" and "obsolete", respectively).
