The 2/8 + 3/8 obviously means sometimes you feel it in 2 and sometimes in 3, but that's not typically how you'd notate that, or is it? I'm sure I've seen things like 6/8 (2/4) written before, but the addition of the + here makes this look really strange to me. I would imagine that any additional metrical info is completely unnecessary anyway if the beaming is used to show the grouping. In notation software, this would probably have to be done with text, graphics, playing techniques, etc., as the meter indication isn't mathematically correct. Just curious how common this practice is, as it's not typically how I interpret additive meters.
