What about assigning this semantic to an empty string ("")?
That would be the default behavior and also the value shown when reading
the file (to distinguish this for explicitly configured values).

(The weirdness of 0, 1, -1, -1, -1  would remain. Maybe switching this
via the mount option could satisfy any user. Admittedly, I tend to
confuse this knob with swap.max.)
