Seems pretty quick, at least compared to Chromium / Firefox ;)
> you don't get to know its status in the meantime
Toward the end of Opera's life (pre v15) either an employee or a member of the community (can't remember which) did actually set up a public bug tracker tracking the status of publicly-reported bugs. It didn't show comments or anything like that: just the original bug description, report date & status. So that was... something at least.
They did also give private bug tracker access to a subset of community members, by invite.
