The affected tests aren't testing the PEP 380 semantics, they're
specifically testing CPython's bytecode generation for yield from
expressions and disassembly of same. Just because they aren't of any
interest to other implementations doesn't mean *we* don't need them :)
There are plenty of behavioural tests to go along with the bytecode
specific ones, and those *will* be useful to other implementations.
