[feat] Consider adopting varlock #492
Description
You might want to consider adopting https://varlock.dev to manage config/.env files.
I believe you already understand the overall idea, as @ladjs/env seems to have some similar goals.
However varlock lets you combine your schema and defaults into a single source of truth, compose values together in more flexible ways, add additional validation logic, etc. It also helps protect any items marked as sensitive with log redaction and leak prevention. There is also a plugin system that helps pull values from various backends, like 1Password, with more on the way.
I'm happy to help implement and open a PR if there is interest.
