There is indeed no commented code for this, but it's a really simple thing to
do. For example, for autoOptimisePtoData, you can add something like
kDebug() << d->mngr->autoOptimisePtoData().project.projection;
at line 304 of importwizard/optimizepage.cpp.

Like I said, activating the equirectangular is done through the pto file (hugin
project file), and already taken care of in the code. Every option to generate
a given panorama is within the associated pto file. The parameters to the CLI
tools are only controlling how to modify the pto files.

Yes, this is ideal. (Actually, it should be a 360x180 panorama, not just 360.)
