[Tagging] Best practices regarding implied tags

[Janko Mihelić]

There are a lot of big power towers that carry an optical communications
line together with the power lines. Would that be
utility=power;communication?

Adding specific implied information is not wrong, but data consumers
shouldn't rely on them. If someone changes utility=power to
utility=communication;power, or if someone outright deletes the utility
tag, that power pole is still correctly tagged.
