Yep, these are great points. There is no way to punish signing the wrong
thing directly, just not changing your answers without risk to funds.
One of the interesting things is that upon a single equivocation you get
unbounded equivocation by 3rd parties, e.g., you can completely rewrite the
entire signature chain!
Another interesting point: if you use a musig key for your staking key that
is musig(a,b,c) you can sign with a until you equivocate once, then switch
to b, then c. Three strikes and you're out! IDK what that could be used for.
Lastly, while you can't punish lying, you could say "only the stakers who
sign with the majority get allocated reward tokens for that slot". So you
could equivocate to switch and get tokens, but you'd burn your collateral
for them. But this does make an incentive for the stakers to try to sign
the "correct" statement in line with peers.
