Takashi and Jiri mentioned that the effort to add SPDX tags to files which did
not have licensing was discussed at the maintainers summit and it was agreed
upon there that this made sense. That is wonderful.
Naturally, even despite this, some still have their own questions about this
work [0]. And some others seem to actually have pointed out that the work might
have some technical issues [1] likely worth considering.

This secondary however was not.
The only sort of explain about this came from Philippe Ombredanne recently [2] on
the generic effort questioned by Christoph.

But this begs the question that if there is still questions, issues pointed
out, and request for a bit more open discussion about the *first* SPDX effort
of adding a tag to files which have no license, if there was *any* due process
for creating consensus for also going along with this *secondary* SPDX effort
of license *simplification* by replacing old boiler plate license tags with an
SPDX tag.
At least internally within SUSE I can say so far that we are surprised by these
patches and work. We did not know, and this is the first of communication of
such effort.
Don't get me wrong, these simplifications make perfect sense to me! But in
dealing with licensing considerations before on Linux I've learned through
feedback from you, Alan, and Ted and others to also be *extremely* careful and
sensitive about licensing annotation matters, and this type of change seems to
likely deserve a bit more community consensus than what this seems to be
getting.
Not even an RFC. So why rush this work in?

Completely agreed, all this stuff is rather silly, however which tag is used,
when, and how seems to have never been discussed and vetted anywhere to my
knowledge.
Below I leave two examples of the patch, but leave in place the diffstat.
