Shall we make -dsuppress-uniques default?

I asked this on IRC and didn't hear a lot of opposition, so as the next step
I'd like to ask ghc-devs.

I literally never need the details on uniques that we currently print by
default. I either don't care about variables too much (when not comparing the
output with some other output), or I need -dsuppress-uniques (when comparing
outputs). The problem is I have to remember to add -dsuppress-uniques if I'm
going to compare the outputs, and if I decide to compare outputs after the fact
I need to re-generate them with -dsuppress-uniques. This takes time and effort.

If you're also of the same opinion I suggest making -dsuppress-uniques default,
and providing a -dno-suppress-uniques (if it doesn't already exist).
