future of grub commands setup and install ?

[Treutwein Bernhard]

according to the wiki the commands install & setup are "unecessary".

I do consider setup (which itself uses install) as "desirable" at least. 

What are the opinions about it?

Background: I rarely have Linux installed on systems, where I'd like to put
grub on and I have used setup to put grub there (see:
http://www.lrz.de/~bernhard/grub-oberon.html).

regards & thanks in advance
