It feels like I've seen this come in a few times, I've said no, it
keeps coming back, I gave in.

Basically the policy is trying to keep things as sensible defaults for
the majority of users. Many of our users are concerned about build
time, space usage and minimisation of dependencies.

These things do change over time as our userbase changes and as the
demands and expectations from software changes.

In this case its fairly hard to figure out that tweaking this option
breaks emojis and libpng isn't such an uncommon or problematic library.

Its hard for me as the maintainer of all this to get a decent feeling
for how people feel about some changes so its also based a lot on feel,
there is only limited patch review a lot of the time.

If there is strong demand not to have this, we can revert it. I'd like
to see how many people do/don't want it and see a few more opinions on
that though.

Cheers,

Richard
