Glad I'm not the only one.

Exactly - a lot of CEX's now refuse to accept any coinjoin BTC, which isn't a problem for most plebs but it absolutely affects fungibility and matters for wider adoption.

Hopefully as non-custodial lightning wallets continue to improve, it can more easily become the norm for actually spending BTC as it already is in ES, and if we're all using LN the sats are pretty much fungible since once they've been zapped through a few different wallets it becomes close to impossible to link them back to the original on-chain deposits.
