Sadly, for at least 25 years all dryers now have come with an auto dry cycle. And the timed dry cycle has been shortened down to 70 minutes.
IIRC, I have never seen a Whirlpool dryer from the 70s onward that did not have an auto dry cycle.
Though to be fair auto dry does not add any appreciable complexity to a dryer.
The ones who did timed dry on several BOL models with common features than added an auto dry on the next step up was GE/Hotpoint. These I think these were by far the best timed dry dryers in existence giving you extra large capacity, temps, and at least 135 minutes of dry time- great for 120 volt conversions and very large/bulky loads being dried on knit/low settings.
