Sorry to interrupt, but you didn't test COMPASS yet.
(Compass is not HarpeX, these techniques are very different.)
Otherwise: You need the R channel to do proper upsampling from 2nd to
3rd order.
Nobody has tested this on this list, at least I did not see any such
test resuklts yet.
Before speaking about limitations things should be tried and evaluated?
Best regards
Stefan

However, you can generate the R channel (which was the first step) AND
upsample from 2nd to 3rd order.
Yes, you can, but, as with any parametric (non-linear) process, you
need to understand its limits. With complex soundscapes, the quality
of its performance breaks down.
Creating a good quality R-channel from an excellent first-order
B-format recording is one thing. Creating all of the third-order
channels is another.
