Yep, but if in even 1% of apps it would make a welcome or necessary
difference, then it's worth it. That's a lot of apps.

It'll work even better on a tighter binary format. Less compression ratio,
but the amount of information in a binary-XML file is less than the amount
of information in a text-XML file. And there isn't always the software and
processor time / memory buffers available for data compression engines.

Simplicity? Parsing XML is a complex task, meaning writing parsers is
harder than it would be for a binary format.
