You do need to guarantee that your bank switch register powers up in the correct state. Which might be a little tricky with only the standard rom signals. But yeah if you're only allowing a switch in your special kernel then you don't need any magic sequences, but I quite like the idea of being able to switch. It would for example allow you to create a kernel that has both tape and jiffydos routines in, with automatic switching between the two 8k images.
