Well, no and yes ;-)
I was only talking about keys that have followed the "approval process" and 
got accepted.

But out of those 4300 I guess we have at least :
- a lot of typo errors
- keys defined nowhere
- keys rarely used
- keys deprecated
( that would make a rough 90% I guess )
Those might have to be corrected in the DB or documented in the wiki

This has been discussed earlier, and I definetly think we have no choice but 
this one.

The question then is "what are core features" 

To my point of view, maybe something like 50% of map features keys should be 
move to "secondary pages", just like sac_scale, trail_visibility for hiking
and piste:* for skiing are.

And other still on map features should be moved to secondary zone
like :

while keeping a "thematic link" 

But I am not the one to decide, so maybe we should start some pages 
about "what are not core features"
