That is what Adobe's DNG was supposed to do.

DNG basically provides a way to perform this raw "dump" along with the
attributes necessary to decipher it all.

The most severe case is if the camera vendor goes bankrupt and its web
sites and support channels suddenly shut down forever, destroying the
ability to obtain and install the proprietary software necessary to
decode existing files.
Apple OS X users have become accustomed to existing software suddenly
not working correctly anymore after an OS upgrade and depending on
software vendors to be able to provide a version which works on the
new OS. Likewise, Windows users sometimes find that their old
software does not work well after a major system upgrade. Given these
circumstances, it really does not take long before things unravel.
