I don't think so. Once gzip Pre-Depends on libc6, it shouldn't be
possible for dpkg to get into a mess because it's unable to fork
programs again. The packages you mention below are all essential,
dpkg can validly assume they'll be installed. And because of their
Pre-Depends gzip, tar and fileutils won't ever be in an unpacked but
unusable state. I think the same applies to ldso too.
(If someone's forced the removal of an essential package all bets are
off, so the only valid issue here is upgrading, as far as I can see)

No; I think there are valid uses of Pre-Depends for non-essential
packages.

You can't make shared library packages essential (Policy 2.3.7).
(libreadline2 being Essential would have made the upgrade to
libreadlineg2... interesting)
Actually libreadline2's Pre-Depends may well be bogus, certainly when
I added it, it was for the wrong reasons (I was confused as to what
was responsible for ensuring {/usr,}/lib/libc5-compat was in
/etc/ld.so.conf), maybe Guy has another reason for keeping it; I'm not
sure. Guy?

The version I can see (5.004.04-2) has only a Depends. Perl-base is
Essential and it's Pre-Depends are definitely a good thing, for, I
hope, obvious reasons.

I'm not sure why elvis-tiny has Pre-Depends, I'm not convinced it
should. I don't know enough about netstd to know if it's Pre-Depends
is valid. One other package that certainly shouldn't have Pre-Depends
but does is e2compr.
