Dang. That sounds nice, actually. Even if the pressure isn't quite
linear, and it's effectively "only" equivalent to a 270bar linear
expansion factor (taking the quoted compensation rule at face value),
at 10l you'd have the equivalent of a 105cuft tank in US measurements.

Are these things much heavier than the "normal" steel tanks of that
size (where "normal" is the same size at traditional pressures? The
Worthington X7-80 is a 10l tank - 80cuft in imperial - and weighs
13.61kg empty)
