No, this requests to upgrade *all* packages of the same source
(well, at least in the TUI, which I normally use, but there is
the same issue in the TUI).

See above, but in any case...

This doesn't work with an upgrade either:

qaa:~> aptitude upgrade -s

The following packages are RECOMMENDED but will NOT be installed:

77 packages upgraded, 10 newly installed, 10 to remove and 22 not upgraded.
Need to get 37.2 MB/43.6 MB of archives. After unpacking 728 kB will be used.

apt-doc is proposed for upgrade, but not apt.

What's strange is that it appears to work for some packages, e.g.
libatrildocument3 replaced by libatrildocument3t64, but not for
other ones (e.g. libapt-pkg6.0 replaced by libapt-pkg6.0t64).
