In light of this announcement from Trezor, I think we need to be careful with assuming Ledger will prioritize Zcash shielded transaction support. Since NU5, Ledger has been a disappointing experience for Zcash users. Trezor has been much better but still, they are not prioritizing Zcash support.
Last time I check, Ledger users still cannot access their ZEC for more than 6 months. And we’re talking about transparent support here. Now I would imagine shielded support will get integrated at a much longer timeline, if ever.
I second this opinion. We have to, as a community, support open-source efforts in this area.
