mod_perl was dropped with the release of apache 2.4 in 2012 (that's a major release, apache is not semver). If I remember well, it was kicked out of the apache repo.

mod_python was also abandoned around the same time. It simply stopped being developed and stopped working (it's crashing on python 2.7).

Basically applications stop running inside apache memory with mod_xxx for good reasons (it's unstable and crashing both apache and the app). Languages moved to a FastCGI interface or to have a standalone web server.
