Just an additional data point: I use tiger:reviewed extensively in
cycle.travel's mapping and routing to make sense of OSM in rural areas.

Bike routing generally prefers minor roads with fewer cars (residential,
unclassified, tertiary) and avoids major roads with many cars (primary,
trunk, motorway). Bike routers will usually try and maximise the use of
residential roads.

Because TIGER class A41 was imported as highway=residential, and much of A41
is dirt tracks or worse, applying these routing weightings to the US would
mean that the router seeks out what are often unrideable routes.
tiger:reviewed is a useful signifier that someone has actually looked at a
residential road and verified that it is a residential road as we understand
it in OSM. So, for the sake of us cyclists, please don't clear
tiger:reviewed if you haven't reviewed a road!

(In urban areas I do agree that tiger:reviewed is often now worthless.)

cheers
Richard
