This was the same on arch. The problem was with anything coming from outside of arch. At that time, python3 migration was not at the same stage, but I'm pretty sure many migrated to python3 without changing the shebang (or missing some).

Python2 goes away in one year, anyway. Packages which still haven't transitioned would give you grief no matter what (if they haven't switched in 9 years it's unlikely that they would switch in 10).

So you would face worse problems with these systems soon. Fedora, like usual, just does that half-year too early.

Packages which didn't migrate are not related to the problem here. Although using versionned binary in shebang is recommended, you can totally keep python (PEP394 says it can be used if compatible with both versions).

So valid Python 3 scripts kept compatible with Python 2 by careful developers could be broken by removing python.

I don't follow. In a future of release of Fedora, if /usr/bin/python points to /usr/bin/python3, valid Python 3 scripts will work just fine

The article mentions discussion about removing completely the python link and providing only python2 and python3.

That's not the actual proposal and people who proposed that backed off from it. So that's not happening

You're seriously underestimating the power of the last minute.
