It could be easily adopted later when point (1) gets a conclusion. > If there is a commitment to work on a generic solution for 19.08, involving other users too, I would be OK to get the support as PMD API for this release. If that is accepted, please bu sure too add experimental tag to new PMD APIs and even add to release notes about intention and that the PMD specific APIs are temporary. And if ABI breakage required, put any necessary deprecation notice withing this release scope so that the development is not blocked for next release. Thomas, Andrew, what do you think?
