Your attempt to paint it as merely a Fedora or Red Hat conflict with Canonical which is certainly ignoring the larger issues at stake here. The debates in desktop-devel list were technical in nature. GNOME Shell has no support for applets and a proposal to include a applet at that point is obviously going nowhere and besides the decision was made by the release engineering team and unless you are going to accuse them of partisanship, you have to accept the rejection and justification for it.
In the future, I would suggest bringing up ideas and implementation earlier to the upstream communities in question rather than as a finished product after doing the distribution specific integration. Otherwise, all the divergence is going to come back and bite sooner or latter.
