This is interesting. Amazing how something so fundamental is still such a pain, and we all build our own half-baked solutions for it on every new project. We've been thinking about this problem for a while now as well, and just launched another tool (https://varlock.dev) that might be interesting for you to check out. Would be very happy to collaborate or just talk about the problem space.

Our tool has similar goals, although a slightly different approach. Varlock uses decorator style comments within a .env file (usually a committed .env.schema file) to add additional metadata used for validation, type generation, docs etc. It also introduces a new "function call" syntax for values - which can hold declarative instructions about how to fetch values, and/or can hold encrypted data. We call this new DSL "env-spec" -- similar name :)

Certainly some trade-offs, but we felt meeting people where they already are (.env files) is worthwhile, and will hopefully mean the tool is applicable in more cases. Our system is also explicitly designed to handle all config, rather than just secrets, as we feel a unified system is best. Our plugin system is still in development, but we will allow you to pull specific items from different backends, or apply a set of values, like what you have done. We also have some deeper integrations with end-user code, that provide additional security features - like log redaction and leak prevention.

Anyway, would love to chat!
