I still think moving the eggs en-masse gives us a better overview,
otherwise we will just forget some eggs. And we can always delete eggs
for which *everybody* agrees that they should go.

That should be the job of replacement eggs, not by providing core
stuff. It doesn't make sense to strip out the srfi's and then add them
again, even when using different names.

Yes (gulp!), I was also thinking about unsafe versions. But I think it
is more important to reduce the core API and reduce the number of
alternatives, which reduces the mental load on the programmer ("should
I use 'string-prefix?' or 'string-starts-with?', and so on...)
