While that may be the reason that this is encouraged, I find the GPX 
data useful for other reasons.  If someone else has driven along the 
same stretch of road that I have, that's one more set of data over and 
above the points that I have.  This enables me to make a better choice 
about where the middle of the road really is, etc.  It also means that 
if I'm mapping a motorway junction that I've recently been through and 
someone else has already been around the missing leaf that I didn't 
drive over, I can complete their and my mapping.

Uploading GPX points might also aid with accountability, but for me, 
that's just a side-effect.
