The idea is certainly not for very project to have its own tags and we 
try to avoid it whenever possible, even try to merge tags when we see 
there are similar meanings (which isn't easy, because mass edits aren't 
allowed unless you basically get 100% support)
What usually happens is that there is local demand to tag something and 
then people come up with a tag. Unfortunately people often forget to 
document it as you already figured out, if there had been a wiki page 
for landing_site and it had been linked on aeroway=helipad someone from 
HOT might have found that tag.

It's certainly a issue and HOT is certainly not the project doing the 
best job when it comes to documentation (Well, it's often documented 
somewhere, but not easy to find). Most mappers usually care about their 
area, which means HOT can often get away with strange tags or tags that 
have not been discussed, because they don't pop up in the neighbourhood 
of mappers in Europe.
I mean of you started tagging amenity=kitchen in Germany you would have 
a 10 page discussion of what kind of kitchen that is, who has access etc.
