Some patents will get a lot of questions, and an advantage of doing things this way is that you can use tag descriptions to provide background information on patents.
There's not a huge cost to having this tag, either.
The whole thing only makes sense as giving a way for the public to more directly communicate with examiners. Keeping the bar very low for examiners is a key component of that.
It will be interesting to see how much of the activity ends up being useful.
