It's the one that changes the least -- given that people seem to have
accepted [1] multiple unpacking, and that you seem to have already (in
the issue tracker) accepted [2] "foo(*a, b, c)"¹, should we continue
with the restriction that "Keyword-arguments must follow positional
arguments, and ``**`` unpackings must also follow ``*`` unpackings"?

That has the fewest changes, but I believe that given [1] and [2] that
these restrictions are either insufficient (hence the rejected
"Original Proposal" from the PEP) or confusing (hence the additional
"Looser rulings").

aka. I didn't mean Status Quo as "change nothing", but "change nothing
other than those two things we already seem to like".

¹ And, by extension, one could also assume you support "foo(**a, b=...)"
