> shouldn’t we future-proof this?

The answer to this is almost always "NO" in my experience, because no one ever actually has good suggestions when it comes up. It's never "should we choose a scalable compute/database platform?" It's always "should we build a complex abstraction layer in case we want to use multiple blob storage systems that will only contain the lowest common denominator of features of both AND require constant maintenance AND have weird bugs and performance issues because I think I'm smarter than AWS/Google AND ALSO we have no plans to actually DO that?"
