Everyone would obviously vote for fast. But we already have that, so why are they not just using the devel channel?
We don't need faster (or slower) releases. We need verifiable releases. Once a month for stable channel is plenty fast enough a cadence, and we could do interim security fix releases if necessary. If you're on stable, that's plenty fast for releases, and people who want faster can switch to rc, or even devel. System updates being released too often on stable channel just makes the product seem immature, while not enough updates makes it look unmaintained. We need to find the happy medium there.
But if we can't verify the reliability of the software, any release cadence is going to be problematic.
