RE: UPAMD updated goals
> a. Life expectancy of 10 years, hopefully more
Yes.
Maybe one question - "life expectancy" as MTBF, or as "to become obsolete"?
> b. same connector for All device and adapter connections if detached cable
It could be hard to gain, as we have broad power range.
There was connector (on one UPAMD) slide, symmetrical, power-power-key-ground-ground; such connector could be made in a way that plug power-key-ground could match also power-power-power-key-ground-ground-ground connector - wider plug/connector for greater wattage.
> c. Power range >10W – 130W delivered power to device and is brand, model, and year agnostic
c1) power range limit, not power - as device could use only 1 W
c2) maybe simply "Power < 130 W"
> d. First adapter must work with last device and last adapter with first device. Standard Compatibility.
"Must properly communicate", because maybe power / voltage ranges could be changed with time
(e.g. UPAMD adapter version 2050, voltage range 0.5 to 10 V, as no device built after 2020 use greater voltage :) )
And some adapter could be made smaller, to smaller devices, and with maximum power not as big as 130 W
> e. Adapter<->Mobile Device communications required for higher power safety >0.7W (down from 7W ie 12-14v@50ma)
I think that 0.5 W could be "simpler" to remember
> f. Standard designed to support Certification testing of adapter and device (and cable)
Yes
> g. Continuous communications growth to support growth of UPAMD capability.
Yes, but with carefully choosen "fall back" mechanism for all messages not present in first version of standard.
>h. Basic power delivery mechanism

OK

> ii. Able to share power for mission critical or business critical applications if willing
Yes
> j. Make independent of rapidly changing technology

Yes.

Yes.
> l. Connector must not mate with any current designs – product Safety issue – no confusion
"any"... we have no directory (nor listing) of all possible strange connectors, so only "any popular" or similar

Of course :)
