Compared to your ideal specifications, my wishes are: support for microSD card storage; battery that easily and reliably lasts a full day with moderate phone usage; fingerprint sensor, not necessarily on the power button; camera decent, not necessarily great (I don't care that much about low light performance, for example).
I'm tempted to sign up even with the specifications as you list them though. Missing microSD card support could be the major dealbreaker. Or alternatively some other user-friendly reliable method of getting lots of files from my PC to the phone's storage, but so far I haven't found any. Early Android versions supporter USB mass storage and that worked pretty well, but the transfer method implemented on newer versions is very slow and never works reliably for me.
Between the inefficiency of non Apple ARM chipsets and the inefficiency of Android, that’s not likely to happen.
Why not? It has happened before.
My Xperia XZ1 Compact:
- runs Android (I'm on Android 10, but might upgrade)
- measures about 14cm diagonally and 8-9mm thick
- uses around 10-15% charge per day of light use (without Google services)
- has a standard headphone jack
- has stereo speakers
- has decent front and back cameras, with no bump
- has a microSD slot
- has a USB type C port
- has a fingerprint sensor (I disabled mine)
- is water-tight and dust-tight (IP68)
- supports VoLTE
- supports WiFi calling
My previous phone was similar, and a bit slimmer. The one before that didn't get such good battery life, but its physical keyboard, swappable battery, and even smaller size made up for having to charge more often.
Obviously, these devices are not common, but they are made from time to time. I'm looking at hardware right now that proves there is no technical barrier. I don't see any reason to dissuade people from asking for a new model.

Not exactly a ringing endorsement of its mobile phone strategy.
And it last a long time not using any services that make Android what it is to most users (ie using Google service) is not a mass market selling point.
