What do you all think about this? It seems to be the first generic combine designed specifically to run post-regbankselect. Should we be going in this direction? Or modifying existing combines so they can work both pre- and post-regbankselect?
Assuming we do want this combine, is there a neater way of writing the "ugly manual regbank preservation" that Matt highlighted?
