  Which version is this for?

  We're trying to do major new features only in v4.  However, that's taking longer than expected.  So we're OK with minor code changes to v3.  But that work cannot involve major code changes.  We just don't have the bandwidth to support multiple releases.

  IIRC, that's already supported in v4.  I'll check with Arran, as he added that feature.

   I'm not sure what that means.  "generic CAs" ?

  We have a plan for that in v4.  But even there, it involves some fairly serious changes, even if they are largely of the form "change A to B".

  We're always interested in new features and contributions.

  My $0.02 would be to open up 3 GitHub issues, one for each topic.  Then describe what you plan to do, and how you plan to do it. We can discuss the changes and see if they can be done in v3.  If it works, we can pull the changes into the main release of v3.

  We *don't* want multiple different versions of v3 floating around, each with different features.  We've seen at least one company heavily modify version 1.1.4.  And then 10+ years later, they're stuck with it.  They don't get the benefit of any of the new features.  And end up re-implementing the features themselves.

  So *small* changes are likely OK for v3.  Large rearchitecture will have to wait for v4.
