Citrea is ramping up to launch a rollup on Bitcoin that would use Bitcoin as the data availability layer. It does not require a consensus change to deploy, i.e., they don’t need to ask for permission. I did not study their protocol in detail previously. Skimming their technical specs, they mention that one type of proof is committed every ten minutes (i.e. 144 txs per day), but I also read that they store all necessary data on Bitcoin, therefore it is not clear to me whether there are more transactions that would write to the Bitcoin blockchain.
If it is just those 144 txs per day, their scheme would be unlikely to significantly impact the fees for other users, but I’ve previously seen an overview of dozens of other similar projects in the making (probably with various degree of success), so there may be multiple other schemes in the future for which we’d prefer that if they must, they only write to the blockchain and not both the UTXO set and the blockchain.

No, that is a misunderstanding.
From what I can see per a cursory internet search, their testnet is about a year old and has over 40,000 txs per day. It looks like Citrea is going to launch regardless.
The only aspect of this that ties into the OP_RETURN debate seems to be that the change could convince them to write their data only to the blockchain, whereas they are currently planning to write data to both the blockchain and the UTXO set.
