Supporting BIP70 by BitPay or BopShop is a cake since it does no more then they did without it.
I am not in opposition but see no reason to be enthusiastic about it. I will once the spec goes
further than what was possible before.

So, if e.g. Trezor ships a firmware update that uses BIP70 to present signed payment identities on the screen, would you support it then?

Yes that would be neat and I would not want to spoil the show. I wish the established identity could be re-used though to send and much more.
