I'm not an authority, but I believe I can:

HgUpdater monitors its configured repos. Sending the mail to ops and
asking for fix versions to be set on specific paths determines which
repos are configured.

Once you push a fix to a repo, hgupdater will create a backport with the
configured version.

In that sense the merge is incidental. I.e. if you push to repo A and
repo B then hgupdater will create backports for both of those repos if
they have distinct configured fix versions.

> b) Imagine the following situation: repository jdk11u is set up for 11.0.3 fixes and jdk11u-dev is set up for 11.04. jdk11u contains a fix for issue A and hgupdater had created a JBS backport item for 11.0.3. At the moment we'd merge back 11u -> 11u-dev the fix for A will land in 11u-dev. Would hgupdater then create an 11.0.4 backport item?

I hope so!
