It's *not* ideological, it's about preventing broken routers.  On most 
routers OpenWrt support, if you do upgrade all you *will* break your 
router because you will end up with a fatal out of space issue that 
results the requirement to reset to factory defaults.

This is because squashfs is *far* more compressed than jffs2 AND because 
with the limited flash on the vast majority of devices it is not at all 
possible upgrade all packages into the overlay jffs2 without causing the 
jffs2 to end up with 0 erase blocks free, which results in a situation 
where you can't even erase files to get back to a working state (try it 
if you don't believe me - dd if=/dev/zero of=/fill.bin and then try to 
get back to a working state).

Regards,

Daniel
