Yes. OpenTimestamps has four public calendars that do transactions to get timestamps into the blockchain. To find optimal fees, those calendars do repeated RBF replacements with higher and higher fees. I run two of those four calendars, https://alice.btc.calendar.opentimestamps.org/, and https://bob.btc.calendar.opentimestamps.org/, and on those calendars I modified the code to do full-rbf replacements.

On the Alice calendar, I'm also paying very high fees (up to 0.01BTC at the moment) to serve as a bounty for miners running full-rbf: https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2022-November/021143.html

I've gotten a few hundred in donations for that bounty, and I'll keep running it until it runs out of money. It's not a lot of money in the context of a mining pool. But maybe it'll help take the sting out of the hate mail full-rbf miners get. :D
