[openstack-dev] [nova][api] GET or HEAD for checking trait existence

I have some questions about plancement API design from
Current implementation of the above patch (PS26) adds GET method for
checking trait existence, and tags.rst of api-wg guideline[1] requires
GET for checking trait existence.
On the other hand, http.rst of api-wg guideline[2] requires HEAD instead.

So there are two questions.
1. Why the part of tags.rst is different from http.rst?
    I checked the review history of
https://review.openstack.org/#/c/155620/ which have added the part,
but I could not find the reason.
2. trait should follow tags.rst? or http.rst?

Any comments are welcome.
