I think a lot hangs on what the data is ultimately for— if you have twenty compressed blobs and you only need one of them at a time, then it's perfect, or maybe if you have a single large blob that you just need targeted random access to.

But if you're going to uncompress it all right at startup, than it's not worth it at all— microcontroller flash is much cheaper and more plentiful than RAM.
