I would say that would be a cool enhancement, as it could save a bit of

Two related points:
1. Walking PATH isn't necessary, but the cwd of the py process should
be inherited from the shell correctly. If it is, then 'py foo.py'
shouldn't need path traversal, it should just look in the current
directory. Using PATHEXT to turn 'foo.py' directly into an executable
command on PATH from any directory is different and out of scope for
the launcher.
Sorry, I disagree that it is out of scope. Looking in the current
directory is fine, when the script is there, but my scripts are seldom
in my data directories, and I want to run scripts (from the PATH) on
data that is in the CWD. I consider this a _very common_ use case for
using scripts/programs, but then if you want to use py from the command
line to tweak which version of Python gets used to execute the script
(if the default one didn't work, for example, and you want to try a
different one), then suddenly, you have to find the path to the script,
and specify it explicitly.
The arguments above apply equally to python.exe. The launcher's job is
to find an appropriate python.exe and launch it, not to locate the
scripts and all the command-line parsing that would entail. If you want
this feature you should advocate for it to be added to Python itself and
it will then automatically work in the launcher too.
