Even in "normal" circumstances this is never a safe assumption.
Let's I save a page [[A]] with {{subst:foobar}} the template for which
doesn't exist yet. Then I create the template, possibly to contain
something offensive. Then you accidentally vandalize page [[A]] when
attempting to do a null (or completely unrelated) edit.
A better question to ask is whether there is some reason to strip
white space at one end of the page but preserve it at the other end.
I'm thinking it would be better to strip it all from both ends unless
we explicitly use __START__ / __END__ etc.
