Yes, very likely, and mine too, probably. But I’ve never had a problem with the (soon-to-be) old grade 2 br chord pattern - even the youngest candidates have seemed to manage. Conversely, I have always been rather glad to leave the grade one pattern behind.
I don't see a problem. There are no accidentals so if you can do one of the two arpeggios or one of the two broken chords, the other is easy. I think most of my students would learn them very quickly.
More generally, I’d like to have seen a bit more joined-up thinking from the board in these changes. The ‘staggered’ idea of doing scales hands separately at first and then together for the next grade is a fair example of this, and seems to be welcomed. Some of the other changes appear a bit arbitrary. I’m hoping they may make sense when we actually start using them - we’ll see.
