Here we are referring to the python2-debug or python3-debug builds, which

Many packages have their *-debug variants. And then some packages (like
kernel) switch even their standard builds to debug mode but only in Rawhide.
Despite all that the *-debug package one occasionally needs is then missing
and one still has to build it locally.
That is all together messy. This is why Microsoft has their debug build of
their whole OS - Windows - called Checked Build:
https://docs.microsoft.com/en-us/windows-hardware/drivers/devtest/checked-and-free-build-differences
The main issue with --with-pydebug is that it changes the ABI, i.e. all
extensions need to be re-built specifically for it (and debug extensions
outside the standard library aren't usually packaged in Fedora). That
makes it much less useful than if it just used less optimizations.
