<sigh> Unfortunately, that is a poor assumption:
If you jump down to "The need to Obliterate" it reads:

I have personally run into many of these cases. They might be rare, but I
strongly advocate that Hg (and others) make it easier to obliterate files
from the repository so long as you have the necessary privileges.
Subversion also lets you export and re-import but this is a cop-out in my
view. This needs to be a lot faster (especially if the files are leaves in
the repository tree) and more flexible to be usable. Imagine Apache having
to take their repository offline for an entire day while they obliterate
files, it's simply not an option.
