I respectfully disagree.
Fixing a usability glitch and accepting a radical redesign of your
interface are completely different.

We're not the first ones to complain about it's interface but they've
not done anything to remedy this despite a complete redesign (which
reduced the level of functionality interestingly).

I see the following in that section:

1) A note that Jenkins is a "glorified job launcher" as we don't use
any of it's advanced functionality (which I refuted - it is much more
than that).
2) Some notes that a proposed patch may be based against a week old
revision. This is making assumptions about how a Jenkins setup would
be made - as we're in control of what it does there is nothing to stop
us trying to apply the patch on top of the latest code in Git.

In terms of checking dependency buildability, once again - this is
possible but we don't do anything like this at the moment to preserve
resources.

As for it not having a declarative configuration, we're in the process
of refining the Groovy based Job DSL script Scarlett wrote. This will
shift the configuration of Jenkins jobs entirely into Git, and
depending on how things work out - jobs could be automatically setup
when new repositories come into existence or when branch metadata is
revised.

This is 100% declarative - and also integrated into our existing
tooling reducing repetition and storage of information, without the
need to convert or replicate the information even temporarily. We may
even be able to eliminate the prepare-environment.py script, utilising
Jenkins functionality for this instead - and allowing us to eliminate
some of the commit hook complexity we have at the moment in the
process.

About the only point left standing is that it doesn't check individual
subcommits, but we've yet to see whether the KDE project as a whole
sees this as necessary - especially considering that the vast majority
of projects would use CI in an advisory role only for code reviews,
and would regular developers continuing to push directly
(necessitating post-push CI anyway).
