Comment:
The form can apply more labels, which could be `unconfirmed` or `needs-triage`, to be removed by a maintainer when confirmed.

Another approach is keeping the automatic labels as-is, but adding to the repo the usage of a `confirmed` label, to be added by a maintainer when the bug in confirmed.  
This might be better if there's interest in excluding confirmed bugs from stalebot.

The idea of both approaches is to ensure that anything claimed to be a bug can actually be found without fumbling with github's horrible keyword search. Searching by labels is more capable and allows searching for combinations, ie: `label:bug -label:unconfirmed` to only find confirmed bugs.
