The keyword above was examples which they clearly were.  Most of
1.0.0.0/8 is in use today despite those examples.  The use of local
test were also clearly examples.  The Microsoft page above advocated
the use literal use of .local which is very different.

APNIC could allocate those addresses if they wished without much
issues.  I'm sure there would be lots of takers even given the known
limitations.  There would be a little extra traffic.  They are
perfect for eyeball only usage.  The real issues arise if you try
to use those addresses for servers.
