There was no real urgency that required this change. A soft fork could have been prepared properly and discussed openly, instead of introducing a controversial change that may expand the attack surface. The lack of serious debate naturally raises questions. It gives the impression that the change was primarily pushed for specific actors or projects, such as Citrea or individuals like David Bailey. If you can’t see that connection, I honestly don’t know how else to explain it.
