First note: There's a lot of different mailing lists with at least some
interest in this discussion, so I've mailed them all for informational
purposes... but let's keep the discussion limited to the kde-core-devel
mailing list!
Back on topic, I have made an initial draft specification [1] for what this
logical module group layer would look like.
In addition, there is a sample JSON file in the kde-build-metadata git
repository, called "logical-module-structure" that one can view to get a feel
for the proposed syntax/semantics.
I didn't want to write another parser, but JSON has no native comment support,
so the documentation [1] is on community.kde.org (though perhaps that's for
the best).
For those with no clue what I'm talking about, the original thread from kde-
core-devel is available from [2].
A point of concern is that currently we already have a concept similar to
this, for i18n. It's possible to specify in the projects.kde.org management
interface a "stable" or "trunk" branch for translation purposes. I don't know
the translation infrastructure well enough to see how this proposal would
impact that feature; I assume we'd want to move scripty (& friends) over to
using this at some point if we go through with it, but it's probably easy
enough to keep both techniques on whatever release checklist we're using now.

They are now CC'ed for review.
One clarification I should make is that I also received a recommendation to
investigate migrating our current dependency data into this new JSON file if
possible. I put the effort into doing this as it would also help make the
implementation of some kdesrc-build misfeatures relating to dependency-data
additions a bit easier, as there's no need to construct an AST and a parser.
Additionally it would permit 'soft' dependencies, which are useful for modules
that can utilize optional features but don't have required dependencies on
other git modules.
However that can, and probably should, be considered separately (though I'll
take comments now, if you have them).

Anyways, thanks for your interest and please let me know if this will work to
solve the problem at hand. If so I will start on integrating within kdesrc-
build, and working with the sysadmins to support within the continuous
integration infrastructure.
