The meta data is not compressed so that is not a problem. What you loose is possibility to "explode" the file and fix something in the HTML code and then regenerate the mobi file.
But my objection is more philosophocal or ideological. I think it is bad of companies to use secret formats but i assume they feel they have to do it. But there is no reason to use a secret format for a file you distribute publicly. That is like just distributing binaries for programs and not distribute the source code which I also do not like.
But I assume if there is a future demand to unpack these files somebody will figure out the compression algorithm.
