Always doing so doesn't make data objective nor an acceptable practice.

There is also open data.
For instance, osmose currently propose to complete all transmission towers
in France with this file
https://opendata.reseaux-energies.fr/explore/dataset/pylones-rte/information/?disjunctive.etat&disjunctive.tension&sort=-hauteur_pylone

Heights are going from 8m to >100m
Nevertheless, height is attached to support, not the line itself.

People aren't forced to produce completed object at first time they map
them.
People may be annoyed with such a question "is the line is minor or just a
line?" if they're not interested.
That's why we are looking for a default meaning for unqualified power lines
as to encourage knowledgeable people to improve their tagging.

Mappers doesn't always use bare JOSM to map, other useful tools help them
to produce data at a high quality level.

Agree with Marc marc, the best situation is power=line which can be
completed with other tags to give more precise and useful data.

All the best
