I have no problem with adding a SPDX line to the top of this file, but
use "SPDX-License-Identifier: GPL-2.0-only" as I was very intentional
with the selection of GPL version 2 only when I published this code.

Furthermore, please do not remove the existing copyright text; although
it's just boilerplate for some, I was careful with the selection of
these words, and I worry the SPDX line only -- despite its useful
conciseness -- may lead to misunderstandings about my intentioned
license for this code.

For the time being, I can't Ack this patch with the changes it makes
currently:

SPDX-License-Identifier: GPL-2.0
Is GPL-2.0 only [1], so it respects your choice of license.

The copyright text:

 Copyright (C) 2016 William Breathitt Gray

Is still in the file.

I'm not sure I understand your concerns here, the SPDX identifier is
a shorthand for the GPL 2.0 only license. See [1] - Linux kernel licensing rules.

One of the biggest benefits with SPDX identifier is that it is hard to verify
boiler plate licenses due to formatting, types, different formulations and so on.

If still worrying, I think we could keep the license text as
well.

Please let me know if I got you wrong at some point.

It is not a matter if you CAN keep a copyright. You MUST NOT remove a copyright.
As long as you do, the series is

I'm sorry, I do not see where the copyright is removed unless you count
the license text as part of the copyright.

Can you please point it out?

I'm sorry for the confusion, I should have wrote "license text" rather
than "copyright text" in my previous message. I agree with the benefits
of utilizing the SPDX identifier, and I see the addition of the SPDX
line as useful, but I would prefer the original license text remain as
well.
