for the sake of humanity ;-)
to be serious, the reasons were (are) below

the point was mainly to avoid confusion for users of multiple UPS vendors.

reaching both goals would be the heaven

in the light of this last point, the free format suits me fine.
I would prefer the term "opaque" or "manufacturer specific" to "free

that we explicitly mention that we refer to the manufacturer's own
naming, not NUT's or any other one.
