I think we need a tag.

There are certainly a few routes that go long distances over multiple
trails, but around me that's the exception.  A typical example is a 250
acre (100 ha) conservation area with a main loop trail, a few access
trails from parking areas at the edges, one or two connecting trails
across, and then a number of trails that are definitely lesser.  It is
true that the lesser ones tend to be unblazed.

I see this as sort of similar to
highway=primary/secondary/tertiary/unclassified in the trail network.
We tag width, surface and speed, so in some sense the classification is
not necesssary.  But it's an important clue about main-ness.  There is
no authority that designates them that way, but in any local area there
is usually a concept of which trails are higher rank.

This is related to the official/informal issue, but I think it's
separate.  What I was trying to say earlier to John Willis is that we
have several sets of properties

  official or not (maintained/suggested by property owner/manager)

  main or not (place in the hierarchy really)

  blazed or not

  whether or not people are prohibited from non-official trails

and now you correctly add to that list

  is the trail part of a named/numbered route

I think it's better to use one tag for each fact, rather than to trying
to group properties into names that imply several of these at once.  I
believe, without enough evidence, that the customs of how these facts
relate to each other vary by region and probably even locally.
