By using BSD jargon, I will describe some other limitations, some of
which you may not yet have gone through:

The OS installer is given the opportunity to partition for you.  If
you tell Linux "to install" it can create multiple slices, eating up
your 4 slices.  If you setup 2 windows OSs, the 2nd OS gets added as
an extended DOS slice.

The limitation of not installing BSD into an extended DOS partition is
a good decision.  It makes it difficult for the MBR code to dissect
the extended DOS partition to find the boot sector.

I am 100% for the requirement of a slice.
