You technically don't have to care, but as it's not always obvious to a
maintainer if he/she can take the patches destined for their subsystem
it's easy that things ends up sitting on the list for longer than
necessary.

dependent as you send it out.

Your current approach works, above is just a suggestion of how to make
it easier for the maintainers, which will help you to get your patches
land faster.
