Initially it may well be a niche activity, but long term roads move
etc, and it's often useful to know historical information, not just
what is current.

I'm guessing by the time this becomes an issue that renderers and
editors will have caught up, but that doesn't mean we should do things
a certain way because the data can't be handled properly at present.

Like OJ W wrote, untagged ways used to be rendered as unclassified but
that changed because the underlying data shifted from just roads to
much more information and it no longer made sense to do things that
way.
