Not a question of should, but of practicality and reality. Linux distro 
installation programs as a class, including *buntu's, usually presume the new 
OS needs a bootloader installed right along with the new OS, usually 
defaulting to MBR as its location, regardless of presence or not of one there 
already, usually making it difficult to either install no bootloader at all, 
and/or install one to some location other than to MBR. It's common for 
multibooters to maintain one independent master bootloader that does little 
more than function as a chainloader, with each individual OS installation 
serving as host to a dedicated bootloader, commonly only with stanzas 
specific to that installation.

Multibooting is as much art as science. The OP has only 4 OS, which provides 
no less than 4! (24) plus 1 possible combinations of installed bootloader.
