IMO installing GRUB can be desirable for two reasons.
1) Obviously, it allows the drive to boot by itself so that you can

change the boot order.
The OP uses legacy boot, but be aware that this won't work the same
with EFI boot : installing a second instance of a Debian system will
overwrite the existing EFI boot entry "debian".
2) It creates a grub.cfg file which provides hints about kernel
parameters and so on when running update-grub from another system.
Should I, or should I not, install the the Buster grub sub-directory on
sdd, the drive on which I intend installing Buster?
I thought I was clear enough in my previous post : I recommend to
install GRUB with Buster on its own drive for the two reasons exposed above.
My understanding
has been that I could install Buster, but not boot it at the end of the
installation,
Why not ?
but rather close buster, reboot the computer into Stretch
as root and then run update-grub in Stretch. Is this still a safe way to
proceed?
Neither safe nor unsafe. What matters is whether you install GRUB with
Buster or not.
My intent is to remove Stretch from the platform once that I'm confident
with the performance of Buster, and the inevitable first problems with a
new version of the OS have been resolved. But now I wondering about that
course of action.
When you remove Stretch, you need Buster to have its own boot loader.
