which clears also the screen - bad if the input you make depends on the 
output of previous commands, the same if your foreground terminal app is 
producing output intended for copy&paste into a mail after finish

a application has *no* valid reason to spit debug output left and right 
unasked, and as said proven by deprecation warnings over years even the 
upstream developers don't read them - so why annoy endusers
