Possibly an "apt-get autoremove" will take care of them.

In any case, you can do e.g. an "apt-get -s purge libc6:i386" and
get an idea of what's going to happen. For the option "-s" you
don't need root rights (actually, better not have them: kind of
belt-and-suspenders ;-)

Cheers

No, doesn't work.

# apt-get purge ".*:i386"
WARNING: The following essential packages will be removed.
This should NOT be done unless you know exactly what you are doing!

Pretty scary message… but since I know I have the amd64 versions, I
typed the phrase and the system still works  ;)

Thanks everybody.

This is strange that you got this message. On my amd64 machine
with i386 as a foreign architecture (and libc6:i386 installed
in particular), I do not get this message.

Note that i386 packages are useful if you use i386 executables.

The libgcc-s1:i386 is marked as "Important: yes" which means that apt
will refuse to remove it by default.  It should not be that way, but
apparently this is a workaround for potentially losing libgcc_s.so.1 on
upgrades from buster.  See https://bugs.debian.org/972936.

Cheers,
       Sven
