No, storing only a hash is enough for ALL timestamping applications.
If you need to broadcast more data then we're not talking about
timestamping anymore, but rather proof of publication.
Unfortunately (and as it has been already mentioned) many applications
don't need proof of publication and yet they are just using the
blockchain as a convenient transport mechanism, but that's highly
It's like if you sent all your mails to all the existing email

It wouldn't make any sense and it wouldn't scale.
A url definitely looks like something that doesn't belong in the chain.
