Why do some folk use a separate /boot partition on MBR formatted drives?

[m654321]

I notice that with some Linux distros, some folk create a separate /boot partition, when installing on an MBR (MSdos) formatted drive.  Is there any reason or advantage gained in doing this? Personally, I can't see any (it's a bit of a waste of space), and prefer to install LL as either /root only, or with separate /root and /home partitions.

As ever, I'm looking forward to hearing your views & comments ...

It's basically not necessary anymore for any kind of system, and for average everyday home users no need, but there are a few cases where it may be preferred.

1) Big non-container multi disk systems, with multi systems and formats
2)Hybrid disks with separate MBR partitions on GUID disks
3)Big secure systems and portable systems (laptops) where you want grub and keys on a USB stick.
4)Big systems with certain administrative low level security features

Many thanks TC for replying.
I'm the "average home user", so the other situations don't apply to me
