It was not directly suggested by Steve, sorry if I was not clear about that!
I get such requests rather often from customers and therefore I'm sick of explaining
why this is a bad idea and quite nervous because most of the time vendors try to hide
issues in their software stack when they ask for such an option.

That said, if we define clearly in which situations UBIFS can safely mount R/O I'm happy.
But please make this new mount option opt-in and disabled by default.
