Yes, I was confused.

It all works fine for me, with one important caveat: I only have one
Linux machine, so Iʼm ssh'ing back to myself. Iʼll see if I can rustle
up a second one in the cloud somewhere.

It fails for me when the remote machine is macOS with

*ERROR*: Could not open file: /dev/ttys005

but I think thatʼs a different bug.

BTW, have you tried doing this with tcp sockets rather than ssh
forwarded ones?
