For that matter, why does the syntax used by Argument Clinic have to

In other words, why does PEP this need to be separated out from the
Argument Clinic PEP at all?
I propose to use this syntax in three places:
1. As input to Argument Clinic.
2. As input to the Python C API, to express the metadata for builtins.
3. As the first line of output of pydoc (aka "help()") when reviewing a
function.
Of these, 3 is visible to users. Theoretically all of them could use
different syntaxes. But consistency is desirable, so it would be better
if these syntaxes were as similar as possible. Python syntax works well
for all three syntaxes, except it does not support positional-only
parameters. It seemed reasonable to codify twenty-year old practice in
a syntax extension that I could use in all of the above.
