I'm not sure I understand what you mean. dpkg 1.20.0 is very old.
Perhaps you meant dpkg 1.21.0. Indeed, on this machine, dpkg 1.21.0
was installed on 2021-12-06 13:39:35. Then, do you mean that this
was actually a bug in dpkg 1.21.0, which got fixed in 1.21.1, but
alternatives settings had already been lost? If this is the case,
is there a way to know which alternatives are missing? Those that
appear in /var/log/alternatives.log* while dpkg 1.20.0 was installed?
Indeed, there's also

update-alternatives 2021-12-06 13:46:17: run with --install /bin/ksh ksh /bin/ksh93 20 --slave /usr/share/man/man1/ksh.1.gz ksh.1.gz /usr/share/man/man1/ksh93.1.gz --slave /usr/share/binfmts/ksh ksh-binfmt /usr/share/ksh/ksh93.binfmt --slave /bin/rksh rksh /bin/rksh93 --slave /usr/share/man/man1/rksh.1.gz rksh.1.gz /usr/share/man/man1/rksh93.1.gz
update-alternatives 2021-12-06 13:46:17: link group ksh updated to point to /bin/ksh93
update-alternatives 2021-12-06 13:46:17: run with --install /usr/bin/shcomp shcomp /usr/bin/shcomp93 20 --slave /usr/share/man/man1/shcomp.1.gz shcomp.1.gz /usr/share/man/man1/shcomp93.1.gz

at this date, and I can also see missing alternatives for ksh.

I can see that on another machine, dpkg was upgraded directly from
1.20.9 to 1.21.1, and I haven't noticed any issue there.
