This seems like a debate about denormalized vs normal form in databases.
Rather than looking at it that way, I think the questions are:
1) How do the various schemes affect our ability to use the
2) How do the various schemes affect the community's ability to edit
I think separate db vs in main db doesn't matter much for 1. The
processing tools are high-leverage and written by small numbers of
people. I don't think we are having a problem now.
For 2, I add POIs with an editor, just like drawing everything else. So
I think having a separate database would be a hindrance if the UI
exposed it. If the UI doesn't expose it, it probably doesn't matter,
but it seems like a lot of work, and I don't understand the gain.

If separate groups maintained the map and the POI list, it probably
would make sense. Does that describe 'everywhere else'?
