I don't agree.
Sure, the commit determins the whole tree end result, but if you want to
sign the _tree_, you can do so: just tag the actual _tree_ object as "this
tree has been verified to be bug-free and non-baby-seal-clubbing".
But that's not what people do with tags. They sign a _commit_ object. And
yes, the commit object points to the tree, but it also points to the whole
history of other commit objects (and thus all historical trees etc), and
together with just common sense it is very obvious that what you're really
signing is that "point in time".
If you want to clarify it, you can always just say so in the tag. Instead
of saying "I tag this as something I have verified every byte of", you can
say "this was what I released as xxx", or "this commit contains my change"

So _do_ exactly that. You can say that in the tag you're signing.
