I didn't write that size was a problem, merely that not saving
defaults means smaller files.
[Though of course this only applies to the default cases]

Besides, I don't think there's much wasted text in the JMX format.
And there is a very good library for reading it (XStream).

XStream has lots of useful features including aliasing.
for example, guiclass="ThreadGroupGui" actually instantiates
org.apache.jmeter.threads.gui.ThreadGroupGui

Remember that the JMX file has to be unpacked into Java classes with
all their fields.

Also of course changing the format would break compatibilty.
There would have to be *compelling* reasons for doing so.
It would be a lot of work for developers and a lot of changes for users.
And it would break some 3rd party products.
