There *is* a world outside of Debian/Ubuntu; Fedora, RHEL/CentOS, and
Arch Linux all use bash for /bin/sh. However, a simple test in the form
of building GCC with dash as /bin/sh, while noticeably faster, showed
that Debian/Ubuntu have yet to fully upstream their work
("gcc/genmultilib: 261: shift: can't shift that many").
As much as the speed difference is promising (and frankly tempting), I'm
afraid we simply don't have the resources to fix everything to work with
dash as /bin/sh.
