I've also seen the opposite mapping issue, where an abandoned railway was
deleted from the map,
when in fact large chunks still exist.

I don't see that railway=razed damages highway=cycleway.

The present day cycleway may well have photos of that same old railway on
interpretive signs.  The current cycleway may in fact be called a "rail to
trail".  Some people seek those out explicitly, because they're associated
with a flat grade and gentle curves.

In cases like this the history is* a part of a present day object.*


--------------------------
Railroads are special in part because they're large and long, far bigger
than any abandoned shop or razed cottage.
They leave a major footprint on the future world, one that's often apparent
well after the last bit of gravel is dug out and planted over.

It's more like tagging "shoe shop in a landmark beaux arts former post
office" than "turn left where the fruit stand used to be".
