How much does it cost to switch? How much effort are you putting into making sure there are no pathological cases while encoding and decoding that have an outsized effect on resource use? How much risk are you willing to take that you don't lose any customer data? If you recompress stored data, how much are you willing to pay in compute? Recompressing at AWS scale is enough IO to burn through many thousands of disks in aggregate—how much does all that wear cost? How much tooling do you need to rewrite? Let's say you save a few hundred million dollars a year after switching. The cost to switch is almost certainly more than a few hundred million dollars. When you make that kind of investment—especially when you're moving away from a very boring technology—you want to be damn sure you know exactly what you're getting yourself into.
