It is so easy to say stuff like this when one's own money isn't what is at
risk.

While I encourage users who would be harmed to chime in if they can,
unfortunately, I think it is mostly wishful thinking on our part that they
necessarily would.  In fact, there is evidence that in practice people
don't.

To illustrate this, consider the example of the people affected by PR #5247
<https://github.com/bitcoin/bitcoin/pull/5247>, which makes unparsable
public keys non-standard.  As far as I am aware none have commented on this
mailing list about it yet even though I happen to know such people do exist
because I've talked with them on Slack.  I believe the person I spoke with
to took over a year (and probably more than two years) to even notice that
the transactions they want to redeem with are no longer standard.  To be
fair, their money that is stuck due to PR #5247 isn't lost yet, but I'm
skeptical they would think or know to speak up here even if their money was
on the chopping block.  The fact that they haven't been able to move their
money in the last *4 years* doesn't mean they wouldn't like it back one day.

While non-standardness is a helpful in dissuading users from committing new
funds to OP_CODESEPARATOR scripts, it doesn't do anything to help users
that may have been caught unaware by the non-standardness change.
Furthermore, because these transactions are non-standard, anyone caught off
guard by the change is going to have a very hard time redeeming their
funds, as we have already seen with PR #5247, a non-standardness change
that is far older than the OP_CODESERPATOR change in PR #11423
<https://github.com/bitcoin/bitcoin/pull/11423>.
