tl;dr

Only add:

tourism=gallery as a new kind:gallery
This should vary in size like museum for features that are tagged on area features (like buildings), between 15 and 17 depending on size and defaulting to 17 if it's a node without area.
Indy's node example is: http://www.openstreetmap.org/node/2026996113, it should appear by default at zoom 17 (not 16 as seen in the museum example below).
Example area feature: Royal Academy of Arts in London with expected min_zoom at z15.

Museum example in pois.yaml:

  - filter: {tourism: museum}
    min_zoom: LEAST(zoom + 1.43, 16)
    output: {kind: museum}

Another reference is outdoor shops which have the double clamp:

  - filter: {shop: outdoor}
    min_zoom: GREATEST(15, LEAST(zoom, 16))
    output: {kind: outdoor}

The other tags aren't supported in the wiki or by common usage in the data, we should ignore them.

Approximate uses of each of these via TagInfo:
