The recommended process for proposing new APIs is to put the proposal to the OpenJDK core-libs-dev mail alias.
Putting the effort into a PR before there is some agreement on the value is premature.
And yes, every change to the spec needs a CSR.

To keep the proposal focused on the APIs, please drop the changes to modules other than java.base.
