Hi thx for your detailed and some technical sharing aspects there.
Perhaps you may try and get a pair of GY ATM2 and try it out
My personal experience changed on 2019, then shortly after was Covid19 . Rarely drive around during CV19 (2020/21/22) , and often keep my tyre air in check.
Used this tyre + -clocked about 40K km ish daily driven (from early 2023 to 2024 ) about 1year half. ( usually short distances )
attached is my current tyre flower example as of may2024. *gonna chg tyre soon, most likey Michelin XM2+ for a peace of mind but was wondering how MaxGuard owners review and experiences will differ further . My hse have another Civic hybrid, the flower pattern tread mm is thicker and get more mileages.

By shallow you mean tread depth when new is lesser than 6 mm or 1/4"?
My XM2 was measured new at 6 mm by ruler. Actual may be 1/4" meaning 6.35 mm.
With this I get 115K km +- per pair with a residual tread depth of slightly higher than (the mandatory) 1.6 mm, i.e 2-2.x mm.
Just imagine, a GY street tyre in 1980s can get repeatedly 60-65K km life span (in a Saga then) -probably with alignment numbers meant for minimum tyre wear as part of the equation.
Tyre technology over the past 40 years have improved by leaps and bounds, be it rubber material technology or tread patttern design or manufacturing technology etc. IME current generation street tyre life of say, 45K km or below (at a residual tread depth of 1.6mm) is unacceptable and it is unlikely to be attributed to tyre brand/model etc.
Of course others' experience or encounters may differs, more so with prevalent adoption and acceptance of fear mongering of tyre safety/replacement at residual tread depth well higher than 1.6 mm.
However despite modern day computer or 'automation', the practice of wheel alignment and its skill and finishing has gone down the drain or longkang!
