Hi Andreas,

There appears to be 121 packages that were real packages in jessie and are
now purely virtual packages in stretch. The list of newly virtual packages
is attached as 'real-to-virtual.txt' is in the form "virtual-name (list, of,
providers)".
Many of them have some level of dependency relationship declared on them.
Filtering this list of newly virtual packages and looking for
reverse-{depends,recommends,suggests} in stretch generates the attached list
in deb822 format 'newly-virtual-deps.txt'. There are 51 stanzas from the
Provides of 20 real packages.
Some crude python to generate these data attached for general amusement but
also to perhaps help you change the output format etc if desired. (Feel free
to ask for further filtering or different output if that would help.)
Would it be useful to have a regular cron job generating this sort of
analysis for stable→testing? Does piuparts already spot these problems or
does it need to be given suitable pairs of packages to provoke them?
(I've only looked at the main archive here; contrib and non-free could be
easily concatenated to the Packages file if desired)
cheers
Stuart
