@astralsparv it's for any type of file at all (that is smaller than 256k) so picoml/piconet is a perfectly good way to use it :)
I imagine it will also be useful for things like storing/sharing snippets, posting custom levels (or puzzle solutions) for games with editors, and as binary blobs that scoresub entries can point to etc -- basically a low level strata for messing around with reinventing a cute internet for kicks
