`makeseeds.py` is used to generate a list of nodes that can be used as peers when bitcoind is started initially, since the fresh node lacks knowledge of the P2P network. A list of candidate peers is initially generated by sipa's long-running node, and then further refined for inclusion in the source code by `makeseeds.py`.
There are various improvements that could be made to this script as proposed by @laanwj.
Complete any of the remaining subtasks outlined in the Github issue:
(1) Determinism could be improved (this is useful for cross-checking)
(1.a) Read ASNs from a file (in progress in #24824)
(1.b) Per-ASN limit isn't consistently enforced?
(2) Bring back onion functionality past TorV3 switch
(2.a) We need a source of non-hardcoded V3 peers, currently the only ones are hardcoded and the seeder hasn't been updated to crawl v3 nodes yet (see sipa/bitcoin-seeder#92)
(2.b) Consider increasing uptime requirements for Tor nodes from 10% as there appear to be enough
