If you don't have the disk necessary for a standard overcommit model to
work, you definitely do not have the disk necessary for a non-overcommit
model to work.
If you were to try to implement overcommit protection on a system
with insufficient disk space, it probably wouldn't have enough reservable
space to run basic system daemons, much less any actual servers.
Read the part again where I mentioned the swap requirements for a
non-overcommit model to operate at the same level as the current model.
