I bought an iPad specifically for this purpose as I thought it would support split-view lol =D
Regarding the UI, there are bigger-screen iPads, mine is 13″ and it would be no problem att all having the UI split in two with that big of a screen. Also they’re becoming increasingly more popular so having the option to split-view if one would like should be up to the consumer. Thank you for taking the time to respond to my request, and I hope you will implement this soon.
All the best
