I cannot actually comment on the original issue… seems asking for a completely new app type for Plex to overcome some heat issue might not be the easiest answer to actually solving a heat issue (from the top of my head: better cooling, separating storage from server, e.g. using a NAS/DAS for the disks).
As for your suggestion: I believe there’s a number of suggestions that had been looking at that from different angles. None of them has gotten much attention over the years – titles can be misleading though
