No, putting a source on an object is not "bad practice".  If the source 
for all of the objects in a changeset is the same then of course it 
makes sense to use a changeset tag for the source rather than repeating 
the same object tag many times, but if different objects in the 
changeset have different sources then it is extremely helpful to other 
mappers to include them.  It's not compulsory (almost nothing is in OSM) 
but it can be helpful.

Best Regards,
