Yes, I have phoenix and use it as my primary.

One reason I sometimes use CashApp is sometimes phoenix gets stuck "Connecting to Electrum" and can't make payments for several minutes.

But the larger point is I'd love regular old folks to pay me via CashApp instead of instructing them to take an extra step with a secondary wallet. Beyond the friction of extra steps, if the user wants only like $5 worth of services, Phoenix is also going to take a good chuck of say that for channel opening fee, which will seem predatory to a first time lightning user.
