Followup to #22372

[hauntsaninja]

Looked through a little of primer, some of the "need type annotation" ones seem bad:

import datetime as dt
a = dt.datetime.fromisoformat("2026-01-02")
b = dt.datetime.fromisoformat("2026-01-01")
reveal_type(a - b)  # Never

[cdce8p]

Looked through a little of primer, some of the "need type annotation" ones seem bad:

import datetime as dt
a = dt.datetime.fromisoformat("2026-01-02")
b = dt.datetime.fromisoformat("2026-01-01")
reveal_type(a - b)  # Never

I modified the stubs in 004ce09 to check if that would be better -- maybe it is?

How do we want to continue here? This feels like it needs another revision in typeshed, so I'd be inclined to close the PR. Or is the latest primer output acceptable in which case I can add a patch for my changes?
