Note that this does change the generated code, from v8SetReturnValueStringOrNull
to v8SetReturnValueString. (For objects like Node, however, nullability makes no
difference for readonly and return types.)

Is it possible for IDBObjectStore::name() to return a null string? If not, maybe
note that in the description so that it's clear that no observable change in
behavior is intended.

Ah, yes, sorry - I meant to comment on that.

I noticed the ? when looking for other IDL diversions. It looks like it dates
back as far as https://bugs.webkit.org/show_bug.cgi?id=58365 where I think it
was added as a misunderstanding.

Name can never be null; calling createObjectStore(null).name will yield the
literal string "null" as the argument goes through the IDL conversion logic.
