It really depends what you're doing. If you're working on developing hardware with a companion app, you're probably going to have a rough time with support, and assuming an iOS update every year, you'll probably need more than just those two TSI too. I think the worst support thus far is probably Facebook/Meta for Facebook ads, and likewise, Twitter, for their respective ad platform. What a terribly broken and unreliable system Twitter has, even pre-acquisition. Breaks in all kinds of strange ways.
