Except the request didn't fail, since the command was sent successfully.

What OP is asking for would require bidirectional communication with the backend, without attaching, which appears non-trivial at first glance.

Perhaps an alternative is some kind of minimal-attach mode, to only receive messages, but that strikes me as even more difficult.

$ screen -r -X select INVALID-NAME
$ echo $?

Please return non-zero status code when the command line option request fails, like in this case.
