A glider with zero static stability will have zero stick force per G and no
tendency to hold any particular airspeed - elevator trim will be
unneccessary. It's easy to confuse this with stability since the glider
will not change its attitude very much in response to turbulence and no
phugiod will be evident. I actually prefer this since, to me at least, it
represents the lowest pilot workload.

I agree - except for "zero stick force per G"... the force per G is a
dynamic behaviour and not static. If you have zero static stability
(which is, as you said, the situation where the position of the stick
at 1 G is the same at different speeds) you still have a positive
dynamic stability (therefore a positive, though perhaps very light,
"force per G") because of the moment induced by pitching speed...
