Your response is exactly why artificial boundaries should be set up. Most of these requests will not be important and they should either be dissuaded entirely or dealt with much later. The ones that are important (note: very infrequent) will be in the hands of someone capable of navigating internal politics despite the existence of a "stop bothering me" canned response.

Every team I work with (very large company) leverages this approach, their productivity would be Nil if they left a direct channel wide open. Back channels exist only where they should exist.

Are you saying Inter-team coms in a large organization should be discouraged? Apologies if I misunderstood your post.
