We cared.  We being the BitKeeper guys.  

BK as of 2002 (bk-2.0.5):
33 documented commands
wc *.c
  67633  225563 1565556 total

BK as of 15 years later (bk-7.3.2)
165 documented commands
wc *.c
 125812  444197 3017977 total

So we doubled in size for all the built in commands but we had 5x as many
commands.  A huge amount of functionality over the bk-2.x era.

The only way we did that was by encouraging and rewarding commits that took
out as much as they put in.

It's possible but you have to be disciplined.
