What precisely does this mean? WOuld those groups be orthogonal?

I really would like to avoid introdcuing the "tags" concept for
now. Would a solution where you give the uplinks appropriate names
(like "uplink0", "uplinkXYZ", "uplink_waldo" and so on) suffice, when
you can then refer to them in a .network file you apply to the
downlinks as "BindCarrier=uplink*"?

BindCarrier= would take a list of interface names, possibly with
globs. If you want to up and down a link "foo" if at least one of the
links "bar", "quux", "piep", "miau1", "miau2" are up, you could write
this as "BindCarrier=bar quux piep miau*".

What would introducing the "tag" concept give you beyond this very
simple schreme described above?
