This is a contradiction. "--force" means "I mean it, dude", and not "I
mean it sometimes". It would make sense if this sentence were "This is
meant to make `+refspec` safer to use."

Do you intend to require users to opt in to safety by saying --lockref
until the end of time? Which makes it actually usable only for scripts
and aliases. How do you override when the safety triggers, e.g., in an
alias that uses --force --lockref? Add --i-really-mean-it?

Or do we want to make --lockref the default at least for cases where
necessary ingredients can be derived automatically, perhaps in Git 3.0?
Then, how do you override when the safety triggers? Add --i-really-mean-it?

IMO, the way forward is:

1. Teach users to use +refspec to force-push. Do not encourage 'push
--force'.

2. Add --lockref as an opt-in for +refspec. Do not apply the safety to
'push --force'. (Current users and scripts do not see a behavior change
because they do not use --lockref, either.)

3. Make --lockref behavior the default at least for +refspec. Then 'push
--force' is still able to override the safety.
