Client Hints - name of the Model

[ghnp5]

Hello,

First of all - Thank You very much for implementing the client hints! I'm currently testing the released version.

Given this User Agent:

Mozilla/5.0 (Linux; Android 10; LM-V405) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/100.0.4896.79 Mobile Safari/537.36

It reports the device as being:

• Chrome Mobile 100.0.4896.79
• Android 10 (Mobile)
• LG V40 ThinQ

I'm trying to experiment how would Matomo detect if I use a reduced device, as indicated in: https://www.chromium.org/updates/ua-reduction/

Sample UA Strings: Final Reduced State Final Reduced UA: Mozilla/5.0 (Linux; Android 10; K) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/93.0.0.0 Mobile Safari/537.36

So I'm sending:

User-Agent: Mozilla/5.0 (Linux; Android 10; K) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/100.0.0.0 Mobile Safari/537.36 HTTP_SEC_CH_UA_PLATFORM: "Android" HTTP_SEC_CH_UA_PLATFORM_VERSION: "10.0.0" HTTP_SEC_CH_UA_MOBILE: ?1 HTTP_SEC_CH_UA: " Not A;Brand";v="99", "Chromium";v="100", "Google Chrome";v="100" HTTP_SEC_CH_UA_MODEL: "LM-V405"

However, Matomo is no longer detecting as "LG V40 ThinQ", and simply returns the model as is: "LM-V405".

Same for "Moto G (4)", which used to be detected as "Motorola Moto G4".

Is this a limitation, or the expected, or something planned for the future?

Thank you very much!
