It suggests that the current theory of gravity is rather like the idea
we used to have that there was force 'due to vacuum', rather than air
pressure.  It proposes that the real cause of the gravitational effects
we observe is not an attraction but a pressure.

The concept is that a force acts on all bodies equally in all dirctions.
When two bodies with mass approach each other, each shields the other
from some of this force and the remaining forces propel the bodies
towards each other.

I don't know how it would be possible to test whether this was in fact
how 'gravity' worked and whether it was possible to differentiate it
from the current theory, as the two would appear to have identical
observed effects.

 
I still go with this:
 https://en.wikipedia.org/wiki/Le_Sage%27s_theory_of_gravitation#

It was an interesting explanation in the light of the way things were
thought of at the time: physical particles and elastic collisions.
Voight's explanation makes sense if you simply conside "a force" without
trying to evoke an explanation for that force.  We can be fairly certain
it isn't caused by physical particles or electromagnetic waves, but who
is to say there isn't another 'thing' in space that we haven't
identified yet.

I agree with you: rather than saying this theory is impossible because
we don't know anything that could cause it, why don't we say this theory
could point to something we don't know about yet.
