Appreciate your concern, especially for the amount of time that users spend
editing data and creating tags.

But just because we originally invented a rule/guideline doesn't necessarily
make it the right rule/guideline. If something comes along which ultimately
is better then we should use that as part of the evolution.

I'd also point out that the map features listing was not created originally
for osmarender. In fact osmarender originally did not support it so we have
already been through one evolution cycle with respect to the tags osmarender
understands.

Hopefully any new set of tags we jointly come up with will be reasonably
backwards compatible, however it's a real likelihood that we will need
people to create scripts that add new tags (based on any new schema) to
existing db features that carry an existing tag that is being deprecated or
dropped in terms of map rendering with osmarender or whatever.

Cheers,

Andy
