Debian bug 863002 doesn't explain why it would be better, as the original bug 
report is evidently a case of misunderstanding how PATH works.

Although we used to do it the way you're suggesting, the current way is better 
for users who want to specify their own 'grep' command with their own option 
preferences, and to have these preferences also apply to 'egrep' and 'fgrep'. See:
