Hi,

Even though I agree that it may be easier to identify for a
non-developer, I am a bit skeptical as Dell has a pretty weird naming
convention which sometimes results in the name being non-unique.
In particular case - 9345 - 9 stands for XPS series, 3 stands for 13",
and 45 would typically be the last digit of year + 0 (so 40), but with
the introduction of last year's ''13 Plus"series they added a 5. At
present, this is unique, however in 10 years it may not be.

I have recently hit this issue when working on Dell XPS 15" 2024
(9530), which has the same model number as Dell XPS 15" 2013 and led
to huge confusions. Only way to distinguish them is by codename
('fiorano' for the newer one), or using a complete name including the
year... The codename on the other hand is easily searchable both in
the source code and online.

I tried to browse the source code for existing notation, but didn't
find anything strongly supporting one or another way, so decided to
follow Microsoft Surface's example with codenames ('romulus').
Codenaming is also imperfect though, as in Dell's case it typically
refers to chassis, rather than _the_ particular device, which
typically lasts several years. Typically throughout chassis generation
internals stay +/- the same, but we can't know if any of the changes
would be breaking. Perhaps then, `x1e80100-dell-tributo-9345` and
`dell,tributo-9345` respectively, as this would be the shortest yet
most complete description? 'Tributo' already implies its XPS 13" and
chassis variation (touchar, hidden trackpad etc etc), '9345' implies
XPS 13" of 2024 (?) and in combination with chassis variant pinpoints
the model.
Otherwise, if it's strongly desired to use marketing names it can be
reduced down to `x1e80100-dell-9345.dts` and `dell,9345` altogether as
9345 implies it being both 'XPS' series and 13", and we can hope that
by 2034 Dell won't repeat the same mistake with naming. Curious to
hear maintainers' opinions as well.

P.S. I've sent the V3 version of the series, it probably makes sense
to move this conversation there for visibility.
