You’re very welcome!

It would save my thumb some pain from having to select all the modules! :D

I am fine with dropping Python 2 support all together. The only major package left that requires Python 2 for building is nodejs and that has a pending patch anyways.

require python2; no package requires python2, but for some optional
parts:

    avahi           -> auto support
    cracklib        -> auto support
    jailhouse       -> opt scripts
    libdnet         -> opt module
    libpwquality    -> auto support
    nfs-utils       -> auto script
    nmap            -> opt script
    owfs            -> auto support
    pcm-tools       -> opt script

    'opt': explicit with Config.in option
    'auto': implicit with .mk conditions
    'module': builds one+ python module
    'script': installs one+ python script
    'support': generic python support (ie. bindings?)

I am totally fine with dropping python2, if we accept the loss of the
features above, an d I think the loss is acceptable.

Note: I haven't had a look at the python-packages. For those that are
python2-only, and that have a python3-compatible version, we bump to
that version, otherwise we drop the package.

Agreed, there isn’t a lot left. I was working on the larger packages first (node, Polkit) before I sent a patch removing python2 altogether.
