Compiling and building debs almost always worked for Mint, it just takes a bit of time.
Granted, the docs gave issues for as far as i can recall back, then again i rarely build debs.
I always aim to find the simplest way to install, so new users do not have to go through a bunch of hoops and get lost in the way.
As for Python, i really liked it ... i said liked, past tense. Now it has become a headache of huge proportions.
Now with Debian it is very easy, a single line and it is up and running.
Again, granted you do not bump into Debian messes, they also tend to do a lot of those, like, yesterday i downloaded the Hybrid ISO with Mate desktop, installed, installing LinuxCNC fails while building the kernel, but LinuxCNC installs and runs OK, without the RT kernel as it insists on having some raspi (raspberry PI) stuff despite being a 64bit AMD version. Had to delete 3 files for rpi stuff, on a 64bit AMD version!!!
After removing those files, everything works perfectly well.
Just to be clear, that is a Debian Mate issue, XFCE version does not seem to have it, and i have not tested other flavors/versions.
