[Tagging] incline default unit ?

My understanding is that with some numeric OSM tags that have default
units, we do not explicitly list the units in the tag value.  For example
if we tag a highway with maxspeed=60 it is understood to mean 60 kph.  If
we want to state the maxspeed in terms of mph, then we would lists the
units,e.g. maxspeed=60 mph.

I think the specific question at hand is, is there harm in using "%" as an
"unit" with the incline tag as it is the default "unit"? (I am putting
"units" in parenthesis to hopefully avoid the discussion of dimensionless
