Yeahbut schema.org has /already/ created hundreds of schemas. How many 
are meaningfully used? 10? Take the example at hand. Is anyone doing 
anything with DaySpa? What about its parent, HealthAndBeautyBusiness? Is 
anyone using that? If there's no real usage, then why create a sub-type 
MedicalSpa? That's just another schema that no one is using.

There's a sense here that there's no harm in creating new schemas, but 
there is. The community is expending resources creating new schemas, and 
authors must search an ever-expanding number of schemas to find the 
right one. So there's a cost; what is the benefit? In many cases, there 
appears to be none.

Search engines ignore most schemas, afaict. In the past, when people 
have asked if they'll be used, the answer is, "you never know". IMHO, 
that's not good enough. There's an implication that using e.g. microdata 
with a schema.org vocabulary will have some benefit to the author. I 
think that implication is disingenuous.

Steps 2 and 3 don't seem to happen very much, except with a handful of 
vocabularies.

I realize this is a chicken and egg predicament. Search engines can't
consume a schema that no one uses, and no one will use a schema that 
search engines don't consume. But it seems to me that we should take a 
bit more of the "pave the cowpaths" approach. What are authors currently 
doing, and what are search engines currently doing? and use that as a 
model for vocabs.
