I'll argue that you can't fix the later one. One thing that I've observed over
the years of having faster computers is, as soon as you make it faster, people
will write slower software.

Currently the issue is that we have thousands of dbus queries, you make dbus
10x faster, I guarantee that people will write software with 10 thousand dbus
queries and we are no better off than we are today.
