Creating this issue to track a comment @Mitzi-Laszlo raised in solid/process#95.

What would be great to include as well is:
the aim/ scope of the specification
the aim/ scope of the roadmap
the aim/ scope of the documentation
the respective repositories to which proposals in the form of pull requests to the specification, roadmap, and documentation should be made
the aim of each repo and how it connects to this process

Am tracking this separately since it would expand quite a bit the scope of the #95 when it's near the end of the review cycle. Any work towards this can go in new branch / pull.
