I agree. Sure, updating your fork is not automated in any way, but not
forking the repository doesn't make it any easier to deal with

You may do the following:
- fork the original repository
- git clone
- cd macports-ports
- git remote add mp

and then whenever you want to change something you do

- git fetch --all
- git pull mp master
[- git push origin master (or whatever you call your own fork)]

You only have to do that last step when you have something worth
uploading, but the updates will go there automatically. Even if your
fork is not kept up to date, the changes you made in one particular
branch can still be fetched by interested users.

(It actually doesn't matter if you clone from macports first and then
add your own fork with "git remote add myowncopy". It's just a
matter of which one will be called "origin" by default. You can rename
it later anyway.)

When submitting pull request one can create a new branch, make a pull
request, then delete that branch (or delete the fork for that matter).

Sure, but you end up with exactly the situation described above.
In what way is creating an empty repository easier than forking one?
