PTX docs say:

If no sub-qualifier is specified with the .shared state space, then it

Ideally, it's the most generic variant that should've had the most generic name
of `shared`, and the specific subsets would have an additional suffix, but
`shared` already has 10+ years of being in use. For pretty much all existing
users SHARED already means a per-CTA variant, and I think we should keep it as
is. Changing its name to something else will not really buy us anything other
than churn, IMO.
We may consider adding SHARED_CTA as an alias to SHARED. I can see how in some
new contexts it may be useful to highlight the intended distinction.
