Thank you Tim and Jonas! This looks amazing! One quick question; you
write:

By "public recovery data", I assume you mean that security is not
weakened by the data being made public. However, are there any privacy
implications? For comparison, if everyone knows what BIP32 HD path I
use, that doesn't weaken my privacy; but if everyone knows my BIP32
xpub, that pretty much destroys my onchain privacy. Where (if anywhere)
does ChillDKG recovery data fall on this spectrum?
Thanks again!,
-Dave
