Where is this work happening ? I cant seem to find any mention beyond
'the 32bit firmware cant boot a 64bit kernel, so there needs to be
some magic in the kernel to switch, and noone is keen on doing that
work' ( this is across many threads on the rpi site itself. Their own
github issues seem to also be stalled with no real activity there.

that should be fine, its how we ship the present rpi3 content, as a
userland image that boots directly.
