I don't agree that this is a bug that should be fixed.  It adds code that will likely never get called or needed (i.e. there has never been a request for this in the decade long history of desciptors and it seems like a made up requirement to me.  

I concur with Amrin's comment that this "is good enough" and Nick's comment that "it's just a matter of pattern of use'.  I recommend that this be closed as "not-a-bug" and that we avoid gratuitous API expansion for what Larry states is likely "foolish consistency".  

If someone object to recommendation to close and really wants to push for this, I recommend making a business case for acceptance and then assigning this issue to Guido for a decision.  This is his code and AFAICT he intentionally didn't go down a number of possible paths for descriptors simply because there weren't motivating use cases.  To the extent that __call__ was omitted on some descriptors, I don't think it was an accident (most of this code was developed as the same time by the same person with deliberate differences between each of them).   His write-ups for descriptors when they were introduced make no mention of an implied requirement for callability.

FWIW, issue 19072 isn't really related to this one.  That issue is a feature request to support descriptor chainging and it isn't clear whether that should be supported or left as-in.
