Then the tracking could be aware of this and DTRT.

And that works how? By diverting the files away temporarily,
leaving users with a dangling /bin/sh symlink during the pak‐
kage upgrade which almost certainly will lead to a failing
upgrade which will leave the user with a hosed system.

As an issue reporter, there comes a time when you are of the
opinion that what you opened is a bug, but the maintainer dis‐
agrees. This is such a case. This is not a bug in mksh, and
even if it were, the fix would lead to broken users’ systems
and therefore isn’t worth it. Alternative ways to fix this,
#2 in dpkg and #1 is currently a nōn-issue (and if dpkg’s new
metadata tracking is being written, it can be written to account
for this, as I have the right of having been here first).
