I don't think all BIPs lend themselves to this pattern. Can you think of =
another example? I also suspect each ignored flag requires carefully =
defined behavior, so it's probably better to spell that out in the BIP.
I also wouldn't be surprised if this BIP will get superseded in its =

there will be many additional params in the future that warrant =
abstraction.

Most wallets consider bech32 addresses to be invalid. This would allow =
merchants to display a backwards compatible P2SH address and allow =
modern wallets to use bech32. In fact, this should be encouraged because =
it's slightly cheaper for the recipient to spend these funds (but not =
worth even a tiny increase in shopping cart abandonment).
Once the new format has sufficient adoption, merchants can simply drop =
support for old wallets and not use this parameter.
