I can imagine calculating correct stop position being challenging in
case of multi-lane bus stations like
https://www.openstreetmap.org/way/37096072 (looks like
reality) or https://www.openstreetmap.org/way/617387384.
In case of Islington the individual stops/platforms are currently not
mapped, but if they were added, calculating the correct stopping
position will also require the router knowing if traffic in the region
is left hand or right hand - that is, on which side the buses have
doors, and thus in which lane they will be.
Then there is the weird case of
buses run on the off-side, and some buses have doors on the off-sides
for historical infrastructure reasons.
Arguably the exact stopping position doesn't matter very much - does
it matter if you show the bus route on the next lane, 3 m over? But it
does complicate absolute correctness.
