In theory you may have right but in practice I guess most currently used
code would not run correctly on 16bit machines.

In practice you have to run and test the code on all target
architectures to keep it portable. Even though I don't use i386 systems
anymore since more than 10 years, As a developer I really like i386
because I can compile and even run it on my "normal" x86_64 systems to
keep my code 32bit compatible, which is useful for any other 32bit
archs (arm, mips, whatever). Thats why I appreciate any distro, still
offering i386 libs.

I get your point but it's only true if the each application runs only
once at the same time.
