just for the archives: xf86-input-wacom still has ISDV4 serial handling code
in it, we just use inputattach in most setups now. Most contemporary serial
devices such that exist still work directly if needed. But yes, the protocol
4 support was dropped in 2009, so we're talking about devices >5 years old.
