Just because "anyone" can submit to winget, doesn't make it wrong to request officially to the developer to submit it himself so it will be officially supported and promote it on the page and all that.
Also, Winget only accepts silent installations, since I use portable Tixati I don't know if Tixati installation can do it silently or not, so the developer would have to improve that in order to be submitted.
But you are wrong about Torrents and Microsoft, there is technically a bunch of torrent clients and tools in Winget, Winget just has nothing to do with Defender.
Plus if it was necessary, people could technically create their own source and then they would not need winget repository in order to get apps, Winget can be useful without using Store or Winget, but I haven't seen anyone trying to make their own sources in order to bypass any Winget restriction or anything.
But anyway, just use winget search torrent -s winget
and check it yourself.
