Er...now maybe I'm the one missing something.  I don't see the
problem:

Say the LastGood tag was applied on Monday.  Tuesday someone removes
a file and commits that, but LastGood is not moved yet.  Shortly
thereafter, someone checks out via the LastGood tag and, as observed
in this thread, gets the removed file.  In my view, that is valid
behavior; the "good" version contained that file, so out it comes with
all the rest.  It should not cease to appear with the LastGood tag
until that tag is moved further up, past the removal, when the updates
since the last tagging are considered "safe."

If I understand correctly, removing the file from the trunk will put
it in the Attic, so it won't come out when a HEAD checkout is done.  I
also believe that the LastGood tag is intended to move from its last
point to the HEAD periodically when the head is considered "safe."
Putting these two things together, I would figure the removed file,
though it will technically still contain the tag, will automatically
cease to appear in future versions of the system.

Now let's see if I'm about to have to take my turn at exclaiming
"D'oh." :-)
