[Tagging] Bus rapid transit: service=bus vs service=busway vs no service tag

I find it strange to use highway=service without being able to add a
service=* to specify the type of service way, but that's how most BRTs
[1] are currently mapped, for example, TransJakarta, Bogota's
TransMilenio, and the Metrobus systems of Mexicy City and Buenos

I've seen service=busway applied to the ways of some BRTs [1], such as
in Los Angeles' Orange Line and Nantes' Line 4, and its usage has been
growing slowly, but it is not documented. On the other hand,
service=bus is much more common, but the wiki discourages its use [2]
since 2017, although I could not find any discussion supporting this
change. It seems service=bus was used to compensate for "issues with a
routing engine" [2], but no other applications seem to support this
value, and maybe those app-related issues no longer exist.

As of 2019, what do you think is the ideal/correct way of mapping
these bus corridors? Should service=* be avoided on them? Should
service=busway be documented? Should service=bus be replaced with
