While not ideal, you can use out-of-band fee payment mechanisms such as
https://confirmtx.com and https://pushtx.btc.com to get the transaction mined
without an on-blockchain payment. For that matter, you could use a Lightning
transaction to pay for that service more cheaply than on-chain payments those
existing accelerators currently use.
