If you publish an extension as a DEV type, it will be removed automatically during an environment update. However, if you deploy it as a Per-Tenant Extension (PTE), you’ll receive warning emails if the extension isn’t compatible with upcoming versions, and only then will it be removed.
Recommendation: Always publish your extension as a PTE when possible to avoid unexpected removal.
