I find it hard to believe they'll make it official completely, as that's basically giving away free API credits. If they really wanted the benefits of having free API credits they would just do that directly (but I doubt they'd do that in their current situation).

they'll probably just more accurately tie the api credit usage into your pro plan or whatnot so it's more clear what's going on. i just don't expect them to fully ban using the recurring consumer sub for api use
