Quite the opposite; this is a very useful suggestion. Imagine that
update-grub didn't give you something workable. You would (or should)
be glad of the opportunity to roll your own. I do it all the time with
removable devices.

In your case, if grub-install had given you a "root=" line in a stanza
it is possible you would not be booting the SD card. A 40_custom file
needn't have it in.
