then make it an external plugin in its own repository, but I am not
merging code that depends on anything GObject if it is just pointless
dependency and bloat.

My answer might be misleading here. My view on this one hasn't changed.
I want either libusb0 or libusb1. However libusb1 becomes only an option
when all major distros did a refresh and have it available. So meaning
BlueZ will be ported over to libusb1 completely at some point. The point
is closer now than 6 month ago.

This is not personal. I am keeping a watch on the dependencies of BlueZ
and I don't see any need for adding GObject to the mix for the SixAxis
support. Feel free to convince me that GObject based gudev is really
necessary for this. Until then I declare this bloat.

Please remember that BlueZ will run on embedded devices with limited
memory and space requirements. You might argue that these devices don't
need SixAxis support, but I prefer to keep that option.

That is your choice. Personally I really dislike if distros just go
against upstream and start merging stuff, because it takes more effort
to get it into upstream first.

On that point, you haven't merged the Socket fix upstream and also the
Wacom and UTF-8 fix could be send upstream. I know you send some version
of these at least once or twice, but besides me also Johan could merge
these patches.
