I personally would like to be able to enable the UEFI boot mode of the board, so that I can enable Resizeable bar - for the performance benefit and to have the option to add an Intel GPU later. So cleaning up the GRUB situation could help me there - that's why my comment above was completely serious, I'd really look at suggestion.

Because otherwise I see it like you, why change what works. Even the move to Grub 2 with the more complicated config options wasn't all that bad, since it really needed less often to be configured manually. So after a bit I was fine with that.
