I agree the product name / model name distinction is the right frame. It
turns out we can settle the product name fairly directly, though: if I look
my machine up on Acer's support site by its SNID, it resolves to
"Swift SFA14-11" in every region I tried — Japan, US, Australia, UK —
and on the China support site as well. So within Acer's support database
the product name is uniformly "Swift SFA14-11", and "非凡 Go Pro AI" was
only the retail marketing name used on the Chinese storefront, whose page
has since been taken down. It is not even a China-vs-global split — the
support identification is the same everywhere.

I fully agree that web pages are not a sound basis — so I'm happy to drop
page-based arguments altogether. That leaves the two sources that cannot be
taken down: the DMI tables provided by the firmware (Product Name:
SFA14-11, which is also what Windows displays as the model) and the SNID
label physically on the machine (SFA14-11-QWU1 on my unit). Both are
model-name only.

I think the resolution follows from the product/model split itself: the
model property is human-readable free text, and per the conventions in tree
(e.g. "Dell XPS 13 9345", "Lenovo ThinkPad T14s Gen 6") it is free to carry
the marketing name — so something like "Acer Swift Go Pro AI (SFA14-11)"
works fine there, and users who bought it as 非凡 Go Pro AI can recognize
their machine by it. The compatible, on the other hand, is the machine
identifier, and it should correspond to what the firmware reports —
either the model-only "acer,sfa14-11" (my v1, following the DMI) or family
+ model "acer,swift-sfa14-11" (what the maintainers asked me to use on my
series). I'd rather not embed a retail marketing name in the compatible.
I'll leave the final call to the maintainers.

Best regards,
Jianfeng
