Will do.

I have submitted a patch to enable at-spi2 to use dbus-broker in
addition to dbus-daemon.

/gdm/at-spi2/ ?

A priori, I would have thought so, but I have not tried to reproduce
their benchmarks, so I can't say for certain.

It is certainly possible, but I see this as an orthogonal issue to
providing the system/user bus so it is not something we have looked
into (apart from making sure it is possible), and ultimately it is up
to the at-spi2 maintainers what bus implementation they want to depend

On the daemon itself, none to my knowledge (assuming my at-spi2 patch
is merged).

Will do.
