Another alternative is you can point to your fork with  all the changes together.

This is some odd style of work. Please don't follow such advise.

But it is not a dependency. Dependency means something does not work
without another. Or something must be applied in the same branch as
another. None of the cases are here. Drop the statements.

This is no different than all of our regular works. Do you see any of
such comments ("dont merge", "dependency")? No.
