Citrea does not need the OP_RETURN increase.
Here is explanation from sb from your tribe:

Well, did you see the video? I am sure there are ways to improve UTXO stuffing. Also what Super says is the abuse on the UTXO would not be so significant so thats less of a threat than blowing up OP_RETURN to 100 000 Bytes. Also there were mentions that other companies manage to do their tech with less than 80 Bytes OP_RETRUN.
But what we see from the compromised Core devs are intential malicious actions - not fixing inscriptions spam for example.
