This thread seems to have devolved into a discussion about motivations and implications on quality of contributions.
The head post is, in effect, a request for an official feature. Responses from the team seem - to me - to be clearly signalling that Discourse as a commercial entity will not implement this feature.
It seems to me that the next step would be to request a plugin, perhaps as a paid piece of work. If someone wants the facility, let them pay for it.
In my opinion, debating whether or not the feature is worth having isn’t getting anywhere - opinions differ, and always will.
