[Tagging] Extremely long Amtrak route relations / coastline v. water

Excuse me, what is the limitation here against tagging "Extremely long
Amtrak relations"? Some of those Amtrak services, while long, in my
knowledge are still far from the longest in the OSM database, like they're
shorter than the train route between Moscow to Pyongyang, which have been
tagged as a regular relationship with no observable problem to me.
In my opinion, since these long Amtrak service are still just a single
services, with no break or cha.ge of train or change of train number
in-between, it seems outright bogus to tag them separately, and would
confuse anyway who wish to use OSM data to provide navigation involving
such train routes.
