It may be one factor, but it's not really a big one in my
opinion. Depending on species pine can vary a lot (1.88lb per board foot
to 3.07lb per board foot). Where as beech is only slightly heavier at
3.34, red oak at 3.38 and white at 3.54.
Bigger factors are availability and price. At least here in the US, pine
is available in large quantities and is typically cheaper than most
hardwoods. Softer woods (at least in my experience) seem to have less
splitting when frames are assembled, though grain plays a big part as well.
I've personally made frames from oak, pine, maple, walnut and any other
scrap wood I've got handy, and don't really notice a big weight difference
on a per super basis.
