Direction was not ignored. People would be disconnected when their client replied to the DCC request or CTCP ping.

I'm not sure the vulnerable modems would ignore the delay because of patents. Would love if you have any reference. I remember a Smart Link softmodem respected the delay, but an Intel softmodem did not. Always assumed it was an implementation bug on the part of the Intel one.

The US Robotics external modems (from 14.4k to 56k) I had certainly required the pause. You needed a pause before AND after +++, then ATH0 with a CR.

Yep, just as my Smartlink softmodem.
