Comment (by alexkingorg):

 Ok, I'm reading this as: please revise the patch as follows:

 - no "stomp/replace" param (actually makes things simpler)
 - add matching functionality to be able to remove post-thumbnails on a per
 post-type basis

 I generally agree and will proceed with those changes.

 The only edge case I can think of is someone trying to explicitly remove
 support for post-thumbnails from a specific post type when a blanket
 "support it for all post types" has been set. I'm leaning towards that
 "doing nothing" and returning an error/false-ish response. Anyone else
 have a good idea for this situation?
