Hi I have some questions about plancement API design from https://review.openstack.org/#/c/376200 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.
