Yet it does so. Quite well, I would observe. My preferred dependency
mechanism needs a tiny little bit more support, configs in configs. I
will pray for this to happen.

Yuck. I would prefer a first-class build & dependency language, similar
to Gradle. It would provide all the conditional aspects and version
specification for past releases. Also it could be made to callout to
gcc, cmake, autoconf, etcetera. And automatic [git pull; git commit; git
push]. This is the build environment for doing round-trip builds and
investigations, spoken about recently in the vm-dev list.
I am not sure I can express myself effectively, as I don't just want to
say yuck and carry on. I owe an explanation of my opinion. I strongly
dislike the auto-construction of #baselineOf and #configurationOf
methods and their required presence. We should have repositories of
artifacts and dependency specification in a build declaration script.
Call it a .sqm for Smalltalk Qualification Module. This has the protocol
of the new Smalltalk-based Gradle.
