Thanks for the suggestion. We already use your "vanilla BitTorrent DHT" suggestions:

tribler/src/tribler/core/libtorrent/download_manager/download_manager.py

Lines 43 to 51 in b1733cb

	DEFAULT_DHT_ROUTERS = [
	("dht.aelitis.com", 6881),
	("dht.libtorrent.org", 6881),
	("dht.libtorrent.org", 25401),
	("dht.transmissionbt.com", 6881),
	("router.bitcomet.com", 6881),
	("router.bittorrent.com", 6881),
	("router.utorrent.com", 6881),
	]

I don't think hyperdht and libp2p are a good fit for us (nor should they be necessary). They serve "niche" peer-to-peer connection purposes.
