Anyone attempting to do a build using obj directories from that
long ago really needs a different kind of support...

All UPDATING really does (mostly) is tell people when they need
a clean build because something won't work with existing obj
directories (which is arguably a build system bug .... but not one
worth worrying too much about most times).

The (very few) entries that relate to changing config files in some
way could just be left - but even those get a bit stale over time.
And even there, no-one bothers with entries in UPDATING when
the kernel config files need updating, and that's the most common
requirement (if whoever built 8 on 4 has private kernel configs
and tried using those unchanged they would have been in for a
shock).

But for the obj directory removal entries, all that should be needed,
if it really needs saying at all, is that if your last build was more than
a year or so ago, delete the whole obj & tools directories, and build
them again.
