Fair enough

Sorry, I would not qualify an extensive design one email wishlist³ and
some code¹ to publish packages.
Let's look at this from other angle, there is a working technology,
can wishlist³ fit there? Which changes are needed?

I rather meant "overhaul wb/buildd/dak architecture", it would be like
starting from scratch here, with modern technologies, modern
languages, etc.
Which kind of bring us up the next point, as something already exists
in this line of thinking.

Heh... isn' it too early to replace wanna-build? Maybe in the long
long term, it can be considered.
When I am saying "OBS as debian.net service" I try to think that:
   + It provides enough technology to be able to support some if not
most of bikesheds scenarios.
   + It reduces development time to nil.
   + It has enough flexibility to try to fit most of bikeshed dreamlist³
   + It does not involve debian.org FTP archive, nor DSA
infrastructure, nor wb database.
   + It already exists, let's try not to re-invent wanna-build to be
* debian.net
   + Service does not put more burden into official teams which IMO
are quite loaded.
   + Service maintainers are responsible for the server administration
and service maintenance.
   + Gives a pre-view of upstream OBS, which enables users.
   + We get some code running, users using it, then teams can focus on
using it and fit their workflows.
   + This would be the initial development, testing phase.
   + Later, we can discuss on how to proceed further into merging it
as debian.org
* service
   + Easily deployable code base
   + Codebase is easy to extend or adapt to Debian needs (or wishlist³)

In summary, I think OBS deserves a chance to be evaluated and worked
on. Nowadays it should be quite easy to setup and configure.

I do not want to drive you one way or the other, but if your ultimate
objective is support bikesheds, why not try if what's already out
there (OBS) can be made use (fit Debian workflows). Think on
maintenance costs (as in people/teams workload), think on
administration costs, think on QA costs, etc.

So, are you able now to propose a task list on which you would like to
focus and work on?
