You can have your cake and eat it too.  Just don't call the wrapper
init.  Somebody else already suggested leaving the init
implementations alone and stick the wrapper in a new binary that would
need to be enabled specifically in the boot/kernel configuration.

So if grub points to /sbin/einit then it runs the wrapper.  If it just
points to openrc/systemd then it directly executes them and bypasses
the wrapper.  That means that this whole thing only impacts those who
install it, which is the best way to implement something experimental
in the first place.

Granted, I don't know the limitations of the EFI bootloaders that are
out there, but this still seems like something better solved via grub
configuration.  When I implemented systemd in one of my VMs I just
added a grub line to boot back to openrc.
