We can add all of them (including PayTM Wallet), add them to the wmf_civicrm install file and big ol' switch block that normalized payment instrumentjust leaving PayTM Wallet commented out in DonationInterface's astropay_gateway/config/payment_submethod.yaml till we get confirmation that it's working.
