You're right, it might by dangerous if it is misused, but GNU grep uses 
it so we should support this to maintain compatibility. And in some 
cases, it can be really useful, imagine that you always want to colorize 
the output, you can just set GREP_OPTIONS="--color". I'd say that those 
who don't like it, can just ignore this and don't use it all, while 
others who have been using it can keep using it, that's fair enough.
(CC'd obrien@ as he was the proposer, who reminded me of this missing 
feature.)
