b4: workflow for selecting to/cc targets of individual patches

[Maximilian Weigand <mweigand@mweigand.net>]

Hi everyone,

as a very new and inexperienced patch submitter I am currently
struggling to properly prepare/submit a patch set where patches are
targeted at different maintainers and would be interested in the
proposed way to do this using b4:

My understanding (also from reading a bit in the tools archive) is that
the cover letter should be addressed to all maintainers and mailing
lists targeted in any of the patches, while individual patches should go
only to the maintainers (via To:) and lists (via Cc:) they are targeted at.

Using b4 prep --auto-to-cc is not an option here, as all To:/CC:
addresses in the cover letter will be used in all patches (my
understanding, based on b4 send --dry-run tests).

Therefore, the only way I currently see is to populate individual
commits/patches with To:/Cc: lines in their respective trailers, e.g.
based on suitable (manual) calls to get_maintainer.pl, such is used
internally by b4 prep --auto-to-cc. Is that the recommended way?

I have not seen many patches on the mailing lists that contain To:/Cc:
lines in their trailers and am wondering that behavior would be
acceptable? If yes, would it make sense to add functionality to b4 that
would populate individual patches with To:/Cc:, similar to --auto-to-cc
does for the cover letter?

Thank you very much for any help,

best regards

Maximilian
