First place, are these standards mutually exclusive? Is it a problem in
practice to work with both?
Second, this isn't a big deal. I don't believe most people have huge
amounts of uncompressed text laying about, at least not enough to
make a doubling of the space make a real difference. As for compressed
text, almost any compressor should get the text down to about the
same space usage. (Feel free to prove me wrong here with real numbers.)
