In general it might make sense to have the complete list on the key page of emergency, and a
selection on map features.

Be careful not to look into lower absolute numbers for features that exist in reality only in low
Discussing some of your reasonings below:

Quite important in those regions!

Why is that not verifiable? Such ponds typically have a red-framed sign "Löschwasserteich".
Ground-verifiable, not necessarily Bing-verifiable.

This is a good approach to improve tagging of emergency features by aggregating them under the
emergency key, in particular those that are not highway features.

The distinction is that aeroway=helipad is a purpose-built infrastructure,
while emergency=landing_site is a predefined spot that is only used if there is an emergency nearby.
This could be a meadow, and there might be an agreement with the farmer to cut the grass regularly.

Yes. I noted that the language-translations of the Key:emergency page are quite heterogeneous,
some having their own list, some used the Map features list. Probably there should be a template
separate from the Map features template that can be included in each of them. Do you know how to
handle translation of the subheadings in such case?
