This is really just begging on your knees for the various distros to
stomp on each others bootloaders, or alternatively -- and just as badly
-- not update the bootloaders at all.

It is way more robust to let each distribution have its /boot and worry
about its own bootloader.

I happen to run 4 linux distributions on a common computer.  I have noted that each kernel has a identification, indicating distribution, version, and some other informations.  The fear of name collision can easily be handled by agreements, such as is done today. 

A single boot partition will probably be installed on a separate SD, or could be integrated into the motherboard bios.  The bios is a good place as the boot process is an infrequent activity.   With UEFI, the bios boot partition makes sense to me.
