@macflo8, requesting your review here as this tries to encapsulate our Slack discussion. Please let me know if there are particular points I made there that should be included here, and where.

@behnam-zakeri, you asked in today's MESSAGE meeting about a list of model names; you can see here the kernel of it, with TODOs to expand over time. Please let me know if this arrangement and the surrounding text are sufficient.

@khaeru Thanks a lot for extending the reproducibility docs. I think it offers clear instructions and explanations on how the users should work with message-ix-models to ensure reproducibility of their modelling work. The most relevant discussion points from the slack discussion are covered well here.
One point that was also discussed in the slack thread is the possible approaches to versioning/documenting of changes in sub-models (model.materials, model.transport etc.) e.g. via separate sub-model specific whatsnew pages. But this is not necessarily directly related to reproducibility, so I guess this can also be covered somewhere else.
