Any replacement should be at least as quick as the current tooling because the current tooling is slow enough already. The other is logging. I spend a lot of time helping people to debug CI job runs and devstack has grown a fairly effective set of logging that just about any time I have to help debug another deployment tool's CI jobs I miss (because they tend to log only a tiny fraction of what devstack logs).

I know. I'm saying the logging that these other systems produce is typically lacking compared to devstack. So any change needs to address that.

If this is the plan then the logging concerns should be addressed as part of the "don't make it noticeable change" work.
