Yes, I think so but only indirectly. Distinguishing between the "same" community on different instances or rather identifying the more active one is already pretty hard, the only thing one can really go by is the number of users who have joined. The large number of abandoned copycat communities on 3+ servers doesn't make this easier since a lot of these have a bunch of users but are dead.
A technical solution could be some kind of "hotness" score for instances to identify the interesting/active ones.
Sounds very similar to the old Soviet pacemakers with radioisotope batteries. After the collapse of the Soviet Union, records about them got lost and so a bunch of people have been buried with pretty radioactive stuff in their chest. I don't think we (as developed societies) are going to take that risk for some phone batteries...
