yes, you can only describe "devices" and only identical ones. If voltage or
phases or anything else were different (see
https://wiki.openstreetmap.org/wiki/Tag:power%3Dtransformer#Tagging ) you
won't be able to tag it with this shortcut. If they are identical, it is a
nice way to save work. Not sure how often it would be useful, i.e. if the
effort to support it and the added complexity by introducing it, are
justified by its usefulness.

For steps we have the tag "step_count", maybe a simple "transformer_count"
would be an alternative?

Cheers,
Martin
