The problem is that almost no-one follows this recommendation.

An 80 character margin is a simple rule that most programming
editors can enforce or handle automatically.

It is also what is recommended in OpenStack:

    https://docs.openstack.org/contributor-guide/rst-conv/general-guidelines.html#lines-length

The kernel doc guidelines don't have a length rule but their docs
are wrapped at 80:

    https://www.kernel.org/doc/html/latest/_sources/doc-guide/sphinx.rst.txt

The current DPDK "single sentence per line plus wrap at ~120 characters"
guideline is unusual, not supported by editors and, with rare exceptions, not
followed by anyone.

As such I think the guidelines should reflect how people actually
write docs and submit patches, which is wrapping at 80 characters.
