- main reason being it's a burden to always define sentinel errors at global scope, wrap them with `%w` instead of using a string directly - only use sentinel errors when it has to be checked using `errors.Is` - replace all usage of these sentinel errors in `fmt.Errorf` with direct strings that were in the sentinel error - exclude the sentinel error definition requirement from .golangci.yml - update unit tests to use ContainersError instead of ErrorIs so it stays as a "not a change detector test" without requiring a sentinel error
