I'm not a fan of this patch.

There is already a "non-standard" signature warning for
all of these cases since 2012, predating the range of this
retrospective evaluation by over 5 years and yet these
existing commits have been accepted.

The value in actual standardization and effectively
requiring specific signature style tags is quite low.

Anyone that signed a thing a particular way should be free
to sign the thing as they choose.

Most of these warnings would also still be in the tree in
the future in new patches as running checkpatch without
it emitting a message of any type isn't a requirement nor
should checkpatch use actually be required workflow.
