I didn't notice this option but it still wouldn't solve the issue of
completely disabling delayed-acks.

It might be useful to an application that for some reason wants to force
acks, it's not so useful for experiments where you want to completely
avoid delayed-acks. The manpage says the effect is temporary and so it
also seems from the code.
