Any reason why you've gone with amenity rather than man_made for these?  Previously there were 70 uniquely man_made https://overpass-turbo.eu/s/2g2d and 45 uniquely amenity https://overpass-turbo.eu/s/2g2c , and 16 both https://overpass-turbo.eu/s/2g2f .  There are now 234 amenity, but the wiki page is against man_made https://wiki.openstreetmap.org/wiki/Tag%3Aman_made%3Dmounting_block
I don't mind either way (I've always shown both) but some people do get sniffy about creating more things under amenity :)
