Definitely there are many benefits to having API specifications available (SDK generation, testing, etc.) especially if they can come from the providers as an alternate from human readable documentation. Seems like the challenges presented above are due a 3rd party trying to find / produce swagger where none existed (a truly heroic effort). Goes back to providers publishing some type of API specification just like websites provide sitemap.xml so APIs Guru can move to higher value projects!
