Not a good idea. Much better to use the existing filter for this. Otherwise
you may be clashing with plugins and core. It's a hack.

Not true. While they aren't passed to the filter as an argument, you can
still access this information. Because the_content() is used in the
loop, then you can simply use the $post and $id globals in your callback.
