# What does this PR do? During env var replacement, we're implicitly converting all config types to their apparent types (e.g., "true" to True, "123" to 123). This may be arguably useful for when doing an env var substitution, as those are always strings, but we should definitely avoid touching config values that have explicit types and are uninvolved in env var substitution. ## Test Plan Unit
