The C world has recently woken up to the problem of integer overflow. I
used to think, "hah, if only they had used Scheme". Now we are proposing
to include this problem in the *core* of Scheme.

Look, the core of Scheme should favor correctness over efficiency. The
core of scheme should define addition on two integers to yield the sum,
not the sum modulus some unknown constant.

Yes, fixnum modular arithmetic can be useful in some circumstances. But,
please, shunt it off into the library.
