Before sysinstall is simply "made available" as an option, it first needs to be taught how to handle a monolithic txz file because the structure of the system has changed.
Also... sysinstall expects to boot into a RW filesystem, and I don't know yet whether the architecture has changed in this respect. If bsdinstall doesn't boot into an MFS, then having the boot loader set vfs.root.mountfrom.options to "rw" is of little effect (for example, if you're booting directly into an ISO 9660 filesystem which can't be made writable -- unionfs aside).
So, whatever prompt the user is given to choose between sysinstall and bsdinstall... said prompt best be pretty early in the game (if we're going to fork to two different operating environments: MFS versus ISO 9660).
