I wouldn't mind us treating this as an error (at least until we get more experience with the new linker and whether that's reasonable behavior), because in my experience, a mistake like this usually leads to undefined symbols in your link anyway, and it's less confusing if you get an error about the issue right away.

No. Color code sequences are not emitted when stderr is connected to a regular file/pipe instead of a pty.
