-1. We do this because other environment variables may lead to a conflicting set of configuration options, where the wrong region is used to target LocalStack, or `cdklocal` tries to deploy into upstream AWS by mistake. If individual configuration variables are needed for the deploy process (e.g. `AWS_REGION`) these configuration variables can be propagated to the `cdk` command by configuring `AWS_ENVAR_ALLOWLIST`, for example: `AWS_ENVAR_ALLOWLIST=AWS_REGION,AWS_DEFAULT_REGION AWS_REGION=eu-central-1 cdklocal ...`.
