I don't "add" anything in regards to those reference types. In fact it is quite the opposite - those guide entries (just like all the other.ms-* ones) get *stripped* when you run the insert/remove cover functionality.
When the cover has not been correctly identified using other methods like a type of "cover" in the reference, the fallback is to try to guess an existing cover using the guide reference entries of type "other.ms-*". What this change does is add "coverimagestandard" to that list of possible reference types to indicate an existing cover image. Prior to the change, those entries were not considered as possible cover pointers, nor were they stripped. So I believe you will find this change perfectly fits your desired behaviour.
