Trim vs primary controls

My few and sparse posts seem to be vanishing

I have read all the posts in this thread and I think I am raising an issue that has not been voiced explicitly even though I am not 'qualified' to do so.

From Lemurian
A.I bulletin
...
All the major US
airlines were adamant on their policy to
recover first using “primary controls”
which excluded any reference to trimming..."
...
Thing appears to be that on the aircraft type in question; the elevator trim *is* a "primary" control in that it is required to be varied for normal manoeuvering.

Of course, mostly the pilots don't see the behaviour as "triming" (and it surely is not trimming in the traditional sense) since it gets taken care of by the computer. Except this time.

Can anyone see a reason that the seperate trim control lever/wheel/switch exists on this type? Since the stick commands "g" (or load factor) surely the seperate trim control is anachronistic? Does it belong in the same bin as the mixture levers?
