sysvinit -> systemd = IE5 -> Chrome.

Sure, you can browse the web with IE5; if all your favourite sites work with it and they aren't changing, then you wouldn't see any reason to change either.

Meanwhile, a fairly significant number of people would like to be able to use the features in CSS3 / HTML5 - and while 75% of those features can be emulated in IE5 (with several megabytes of javascript libraries and terrible performance), life is easier and better all round if the users upgrade their foundations once in a while.

systemd doesn't care about the kernel per se, only which features it provides. If they want to provide a cgroups-like API (which they should, because it's a great idea in and of itself), then I expect systemd will be ported to it fairly quickly.
