Allow alias

Could you please allow multiple alias to Plausible.
I.e., BASE_URL=https://plausible.example.com
ALIAS=https://plausible.example2.com,https://plausible.example3.com

Are you self-hosting? If so, you can easily do that by setting up multiple sites in nginx (or your reverse proxy of choice) that all point to your Plausible instance.
