I'll have to be be forced to implement PayPal and thankfully, while it's been asked for, I been able to say no in all my projects. My audience is domestic-only (US) and since you can put a card on file easily or use Apple/Google Pay I haven't heard from any customers asking for it (only organizers that pay for the software, and only off-hand). If anyone were to push I'd just quote an absurd number to implement it.
I know Stripe isn't perfect/flawless but I'll do everything in my power to avoid doing business with PayPal.
