Fine, as long as you provide 32-bit as well as 64-bit userland. Otherwise
many programs will pay a substantial performance penalty, as pointer-heavy
programs double their memory and I/O requirements (and Sparc doesn't get
any compensating benefit the way x86-64 does from extra registers in
64-bit mode).
The GNU toolchain has extensive support for multilibs, and other Linux
distros can have 32-bit as well as 64-bit packages installed, but Debian
has traditionally forced people to use chroot to run 32-bit programs
on a 64-bit OS.
