I have some bad news for you: elixir ecosystem is consultancy-driven ecosystem. While at least better than bigtech-driven ecosystem (cough cough), the changes you seek are less likely to happen because

1. They make it easier for consultancies to templatize what they do, which:

- keeps their employees tied to the hard earned knowledge

- keeps their clients tied to their services

At least though you know that those patterns are (usually) common and battle tested (or, at least, will be battle tested - cough cough ash), and unlike a bigtech "their problems are likely to be your problems".
