As Georg noted, only individual expressions get parentheses based continuations automatically. For statement level use of comma separation, it's decided on a case-by-cases basis as to whether we think it is a legitimate usage based on our style guidelines.

That's why 'from location import (name1, name2)' is allowed, but 'import (name1, name2)' is not: we explicitly advise against importing too many modules in a single import statement, but importing multiple names from a single location is often a useful thing to do.

However, while the multiple context expression use case is reasonable, there may be a grammar ambiguity problem in this case, since (unlike from-import) with statements allow arbitrary subexpressions.
