[Question] Use the "cache" array information of the ESI rules block

[boesbo]

Technically, is it not possible to populate the ESI information by interpreting the "cache" array (cache_lifetime, cache_tags, cache_key) that is present in the blocks?

This would make it much faster to migrate from "Blocks HTML output" of Magento to the Varnish one. Tag cleaning (via cache_tags and event: application_clean_cache), TTL (cache_lifetime) etc.
