I agree consensus needs to be changed, but I'm aware of talk around some of these potential issues, and afaik, they are being worked on.
I agree that even locking such transactions (accidentally) for a year wouldn't be good, and needs to get fixed. But, so does Bitcoin!
Hopefully we can all come to some compromise that doesn't break things (that haven't been purposely setup to break thing... or were using some really far-out non-standard method), but still fixes Bitcoin. It is well past time to reign in the abuse, and make Bitcoin about money again!
