Mailing lists have had threads for decades.
You can subscribe to individual bugs in Debbugs, you can't subscribe to threads. Threads also don't have short ID (bug 123456) and don't have metadata like whether the bug is closed.
Broken email clients and careless people break those all the time though...
In the long run, everyone who tolerates email is dead.
