Filter conversations by company data (not only conversation data)

Currently Inbox Views are working solely on conversation attributes and conversation data attributes. It would be so much more effective if we can filter buy company/user data as well... Why?
(a) we need to work really hard to push user/company data into the conversation data, it makes everything much less flexible.
(b) it makes data sticky. If I edit company data (manually or by api after user/company product behavior) , the conversation data attribute doesn't change.
I assume the initial setup was do to resource management, but I think you can afford some more resources on it, no?
