I always remove those when downloading torrents because I'm paranoid they're obvious markings of torrent traffic, more-so than DHT connections.
How would you as a peer connect to any other peers without some kind of seed?
What IPs do you connect to?
You might observe when trimming the tracker list off the URL that sometimes you can't find a peer, that's because you've never used the same client to contact what effectively amounts to a subnetwork that has no overlap with any previous subnetwork you leeched from in the past.
Especially if you're always fetching the same content (e.g. Game of Thrones episodes) it'll probably just work, but you may find it breaks when you suddenly decide to grab e.g. an old copy of OS/2 or similar, representing a set of BitTorrent users with entirely different interests.
