Are you still having problems finding wallet developers that provide full node network access (for xpub privacy)? It seems like I can get really secure Bitcoins using a Trezor, as long as I don't mind trusting wallet service x's nodes with full account details. I really don't like the latter part, however good the former is.

I suppose a workaround is to treat Trezor accounts as dispensable in the same way that ordinary addresses are. There's no upper limit on the amount of accounts that a single xpub can generate, right?
