This is good news for a start. We essentially have a UI problem, and if
solved, will help getting back the most useful bits of the lost data back
into osm.

The most easily identifiable data that I see are those that have name tags.
What if you have a list view alongside a map, which is populated based on
your current view and zoom level?

For ways, this can have additional information like the length of the way
and orientation to assist mappers who lost their tags to identify where the
original way was.

For POIs, you could have the name of the street beside which it was located
and also distance and orientation from the nearest place=* node

There are probably better ideas, but its an absolute shame that clean and
extremely valuable data is lost because the data model does not support its
existence.
