I like the idea of sharing clean URL's. Actually, I use the Pure URL add-on[0] for Firefox which also removes garbage such as e-mail campaign tracking values, both for the purpose of sharing and since I prefer seeing/visiting clean URL's myself as well.

The Chrome implementation using the canonical URL has some edge cases which may be useful to handle, like adding the fragment which isn't part of the canonical URL for the resource yet can be useful to share. Given that this change is only for the share dialog and not for copying from the URL bar, that doesn't seem like a huge problem though.
