Definitely not critical, as I said I'm aware they're unsupported for good reason. However, both features are a luxury I've become accustomed to. I upgraded my car's sound system with android auto in mind, and I haven't carried a wallet on me for a few years now.
Aside from that, I'm all for seeing any de-googled tech grow in future
I took a look at GrapheneOS when I purchased my current phone. Loved it for what it offered but the lack of Android Auto & tap-pay support ultimately turned me away - they're both not supported for good reason but I use them almost daily.
Does anyone know what the situation is with this product? I assume it also won't support Android auto for the same reasons
