Well, I think an argument can be made for making it easier to compile in an alternate default qdisc, from a distro basis.
It is very hard to configure tc correctly otherwise for a wide range of devices, notably multiqueued ones, and htb. This has been the primary barrier to adoption by bleeding edge distros. (OpenWrt went the kernel patch route which appears to be working out well.)
I will propose a patch in a week or so that does that rather than just arbitrarily switch.
