I understand completely how the Dell naming/numbering scheme is confusing. The shortened version down to just the model number could also be confusing. For example, there is an XPS 9520 as well as a Latitude 9520. The 9 basically translates to "premium" not a specific line of business. For what it is worth, I would prefer the dell-xps13-9345 naming and I think we can have to be mindful to avoid a naming collision in a decade.

Completely agree. Although I'm not sure about the name - analyzing
DSDT of Tributo it seems there are quite a few more things defined
than particular laptop utilizes, eg. support for x3 TypeC and x3 USB
MP while current device only has x2 TypeC and x1 USB MP. I believe
these are either leftovers of examples being provided to Dell which
were just left there, or ACPI tables being (at least partially?)
shared between multiple platforms - eg. Inspiron 14" 7441/Latitude 14"
5455 etc. In the latter case (unfortunately cannot test myself due to
lack of hw) perhaps the .dtsi can be inherited by more than just XPS
family. If you/Kemp Bryan could share some insight on that already wrt
to how much is shared (if any), I can split to dtsi/dts with upcoming
re-spin. Otherwise indeed can be done when the next platform is being
introduced.

Yes, will drop 'tributo' altogether. Perhaps "../dell/xps13-9345"
then, to match the proposed compat? Also when Divo/Huracan/Perfomante
will come out, those are still "XPS" but I would guess will have
different firmware files, so maybe it makes sense to be a bit more
precise with the naming?

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.

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.
