Did you follow the thread? [https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=727708]. I know it is a lot to read, but it has everything you ask for. Sysvinit could go on working for a couple of years, but there is a lot of bad workarounds in it, that are held together more by spit than by glue. One example is it's handling of fstab in nowadays systems.
If you have to make a decision sooner or later and a superiour system is available, why not do it now and by that stay in touch with the rest of the linux world?
