The lack of an advertised set of capabilities is intentional so that data can be gathered on what users want the system to do (even if it can't). Unfortunately, this is a terrible experience for the user as they are frustrated over and over again.
This is a problem all over our industry:
- almost every search field (when an end user modifies the search instead of clicking one of the results for the second time that should be a clear signal that something is off.)
- almost every chat bot (Don't even get me started about the Fisher Price toy level of interactions provided by most of them. And worse: I know they can be great, one company I interact with now has a great one and a previous company I worked for had another great one. It just seems people throw chatbots at the page like it is a checkbox that needs to be checked.)
- almost all server logs (what pages are people linking to that now return 404?)
- referer headers (you product is being discussed in an open forum and no one cares to even read it?)
We collect so much data and then we don't use it for anything that could actually delight our users. Either it is thrown away or worse it is fed back into "targeted" advertising that besides being an ugly idea also seems to be a stupid idea in many cases: years go by betweeen each time I see a "targeted" ad that actually makes me want to buy something, much less actually buy something.
Given that they made no apparent use of such information in practice, the unfortunate thing is that they had the idea to begin with.
