@mikewalsh , GRUB2 is about 2 decades old. This is not new. Just that the world have worked together to keep it current with what manufacturers have submitted to keep us rolling on a Linux platform. Still works and world still supports it.
BUT, it will change of course. In fact, except for people like us who are willing to follow Linux, all of this is changing as we go...now!
Look at the world of users and the products provided us, and you can see where we are heading.
Change is forever! Often times as an improvement.
BTW: This offering from @Shinobar is not really supporting a change. Rather, it appears to be a "helper".
