An unlikely situation is that a vendor-specific command in the "low" range (i.e. not 0xc0..0xff) conflicted with an MMC command, so it happened to be enabled. That will now break, but only if executed without CAP_SYS_RAWIO. Nothing will change for programs executed with CAP_SYS_RAWIO. I have not disabled any standards-defined command that used to be enabled, and on the contrary I enabled a few of them, so this could potentially lead to less emails from peeved developers, too. > Is 8 lines of documentation changes enough?

The command whitelist was not documented before. It's quite likely that any documentation except the code itself would not be updated the next time the whitelist is touched.
