No vault schemes that I’m aware of - and certainly none of the concrete examples I’ve done with OP_VAULT - automatically transfer coins after some height, relative or otherwise.
As far as I can tell, the summary of this post is “using timewarp, miners are incentivized to speed up block issuance to claim high fee transactions associated with automatic vault recoveries.” But I haven’t actually ever seen a vault scheme that is vulnerable to this, because the recovery path (in every scheme I’ve seen) consists of both a relative timelock and a recovery key.
Miners might be able to speed up the chain, but they can’t sign with keys they don’t have, so I don’t think the timewarp attack represents some kind of new problem for vaults.
