That is a nice feature of OSM, and I've done this a few times.

But I wonder if there is any propagation delay from OSM to Lyft. When I made some changes to OSM data, I expected the Strava app to pick up the changes for route creation, but they don't receive updates constantly. Instead, it took several months until the changes took effect on Strava.

As an OSM mapper I would not say that debugging and fixing address issue is easy...

It's maybe a little snarky, but the most common issue is relatively straightforward to fix, just add the missing address.
