function to return t when it should have returned nil.

it's not known whether the ownership will be preserved.

Likewise.
(tramp-get-local-gid): Use group-gid for integer, as that's

to mark it as a placeholder. The old value was often wrong.
The only user of this attribute has been changed to use
file-ownership-preserved-p instead, with its new group arg.
