I don't see how a user option to control this could be useful, since
the preferred behavior is not only buffer-local, but also specific to
certain syntactic constructs.  But I won't object to having such an
option.

I also don't see what's wrong with the solution of having a special
function in .dir-locals.el.  We don't pretend that the default Emacs
behavior should necessarily fit all the use cases, and provide ample
opportunities for customizing Emacs behavior for that reason.
Defining a custom fill-paragraph function is a perfectly valid
solution, not very different from having a user option for the same
purpose.  So I'm not sure I understand why you prefer adding an
option, when the Guix project has already solved the problem in a
perfectly legitimate and clean way.
