This is brilliant, and exactly what I was looking for.
Thank you _so much_ for taking the time to write all of this up.

Well, it *is* documented :) And it seems to be the obvious hook:
when loaded, my component creates more components…
Yes, indeed!
I have built a few systems like this, except I've always used hooking
after setup_components to read config and setup the components I have
generated via MMC->create, embedding the logic to do the scaffolding
into MyApp.
Using expand_modules in the way you have to allow components to plug
their controllers is a great hook to use. :_)
Questions:
- am I insane? :)
No, not at all.
You have a fairly scary use-case, but I think what you've done is
perfectly reasonable.
- is there a better / cleaner / more future-proof way of getting the
same result?
At a word, no. There are other techniques you could be using to get
the same results, but they're likely to have the same sort of issues
(i.e. we'll have to think hard about back-compat).
I was more doing a survey to find out how people are using it in real
life, as the current tests for the feature are woefully inadequate for
testing anything other than the most trivial of use-cases.
We can now write some tests for a more advanced use-case like yours in
the Catalyst test suite, and then verify that everything you're doing
is still possible / working when we shift the internals around (or at
worst, that if we need to break something, we can explicitly document
it, and how to get around it in the new version)..
- will the "much better solution" that t0m hinted at still allow me
this kind of contortions?
Yes.
In fact it should make doing them significantly easier and more
flexible, with less hacks involved.
The idea is (and there is a very active branch working on) porting the
component discovery and loading to Bread::Board, allowing you much
more flexibility in how things are wired up.
Cheers
