Not only has it been years since I last have heard of bugzilla, I also really resented it! Moving to a modern infrastructure really improves accessibility for developers. For example, GHC (Haskell Compiler) moved to gitlab a few years ago and while previously it was really hard for me to understand the development process nowdays I can follow pull requests and tickets of features I am interested in without any problem. Previously the system was really complicated and, if I remember correctly, Phabricator, mailing list etc. based. Off putting as a newcomer.
