A locked transaction could pay to an OP_CA= T script with the private key being lost.

Even if it is o= nly in theory, it is still worth trying to prevent rule=20 changes which permanently prevent outputs being spendable.

If at least one yea= r's notice was given, then people aren't going to lose their money,= since they have notice.

Locked transactions could have a= difference expectation than non-locked ones.

In other words, how close to the shores of "administrators of a virtua= l

Miners can collectively vote to disable specific UTXOs and chan= ge the acceptance rules.
