We'll use the feature.  JSL already supports it, and Brian uses it.

The idea is this:  What if someone wants to hand-edit patches ouside of 
JSL?  It's excessively difficult to edit the hex, but would be possible 
if the patch data was itself a bunch of XML.  I don't know of any way to 
automate this (unless we can leech off the XML editor stuff) but if we 
leave it up to the driver, then anyone who needed it could update the 
driver to create and parse it.

It's also difficult and annoying to write such code, so it'd be up to 
the driver writer to take the time.  By the default, we just dump the 
sysex to MIME64.
