Why don't you use the Github issue system?

1. Bugzilla is working famously for us.

2. I've had occasion to use github issues, and was surprised by how lame it was 
compared to Bugzilla. There's no contest.

3. If Github goes dark, we still have our local complete copies of the git 
database. If Github issues goes dark, we lose it all. We control the Bugzilla 
database. This database is ABSOLUTELY CRITICAL to D's future, and not having a 
copy of it is absolutely unacceptable.
