> Aaron, ping. Would you want to introduce new (sub)sections such that id.S and fit.S are properly accounted as sections instead of an arbitrary reserve below .reset?

I think that would be helpful. Ideally we can agree on how to construct that upper end for linking purposes w/o wasting space. Basically make the section small enough (w/ an appropriate alignment) to fit the required entries but not large enough that we don't fragment the space leaving it stranded. We can pursue this path soon-ish, but I don't think we're dependent on it at the moment. Let's wait for Marshall to update his patch stack that includes a normal transit through bootblock and romstage for the new boot architecture. Then we can improve things from there.
