It is been worked on as we speak. Currently Stripe's Apple Pay integration is being finalized and then we will test for final release. My guess is another month.
That is GREAT news.
If you need anyone to help test it when you are at that point please let me now.
I have a site that won't go live for at least another month, but our subscriptions section is installed and could be used for testing (also, I've worked in Joomla extension dev/support so I can provide you with very detailed test results IF any problems were found).
