required: roadmap for pg versions support

I just saw this issue concerning pg 14 on Windows (https://github.com/apache/incubator-age/issues/138). The reply there
`Support for PG 12 and beyond likely won't start until 2022`
is very discouraging, and contradicts [Age home page](https://age.apache.org/#) which states
`AGE is currently being developed for the PostgreSQL 11 release and will support PostgreSQL 12 and 13 in 2021 and all the future releases of PostgreSQL.`
I see now that the readme.md of [this project](https://github.com/apache/incubator-age) states
`To focus more on implementing the openCypher specification, the support for PostgreSQL 12 will be added in the Q1 2022.`
We use in production pg 13 (linux), and going back to 11 is NOT an option (also due to other extensions). Mind you, pg 11 is 3+ y.o. and pg 12 2+ y.o.
I tried to build AGE from source with both pg 13 and pg 14 (on linux), it fails to compile due to changes to pg h files (different failures for the two versions).
I believe that for many organizations, the decision whether or not even to consider AGE as an option depends on its roadmap for supporting various pg versions. Which is what I am asking you to provide. Not in vague statements, but targets for each version - when do you expect to support 12, 13, 14?
Thank you.
