When hydra fails to build a package, does it notify maintainers?

… and there was a situation when the situation from the second quote lead to the first one. It was something with branch setup, and Hydra ended up sending hundreds of email (per person) to a large fraction of active maintainers.

Naturally, this was found an unacceptable failure mode. Nobody since have proposed patches that would even claim to protect from this failure mode well enough that reenabling the emails could be discussed.
