Yes, start with the simplest, best isolated feature first. That will
help get the ball rolling.

I fully understand, and something similar happened to us before. If
project pressure comes in, you can easily be forced off-track and then
have to pay the price later on.

However, it would have been valuable to participate in the requirement
discussions early. That might have enabled us to prioritize features and
sharpening their scope to address your needs as well.

Indeed. Upstream is Isar, not a specific fork of it. By now, we are
working on a number of products that build upon upstream Isar, are
mostly happy, but will surely further improve the core to improve the
usability. Eventually, you will miss those features in your fork, I'm sure.
