Jeremy proposes to change how vendored libraries are handled on developer build, example: https://github.com/ocaml/dune/pull/3575
The main idea is that in bootstrap / release, the vendored copies will be used, but for development, dune will depend on the installed versions of such libs.
This should solve some annoying clashes of system vs vendored libs, for example in tests.
It should avoid some renaming, which is also annoying, and quite a bit of work to do when adding new deps.
The main dev-visible changes are:
- a complete install of dependencies is now needed for development, vs the current setup which only requires some deps
- no more modifications to vendor allowed, patches should go upstream
Recent work in Jenga has highlighted some interesting improvement which could benefit Dune.
4.10 seems ready as dev platform, thus following the current compat policy support for 4.07 should be dropped.
configurator setup has been improved, this should mean people on
older OCaml + ocaml-secondary-compiler are fine.
Move to 4.08 is interesting as the custom future_syntax preprocessor
goes away. This will enable some nice use cases such as instrumenting
dune itself with bisect_ppx.

Quite open at this point; the goal is collect ideas and brainstorm a bit.
For example "writing a rule is annoying because of this problem" kind of feedback.
Emilio did collect a list of people using Dune for Coq, it will eventually appear at https://github.com/ejgallego/coq-plugin-template .
Lots of discussion among Coq devs about how to better support "Coq's native compilation" still didn't converge, but progress has been made.
