Updated patch with docstring amendments. The tty test you're asking about was already in place, I merely added the missing frame argument that ensures the test is against the source frame rather than the ambient selected-frame. As to its utility, I can go only by the docstring sentence that reads "If the terminal is a text-only terminal then also select the new frame." Seems to have originated with this commit 2c662e6d66165db8ead2f4d19a61af521807b8ba in 2021 when clone-frame was introduced.
