As I noted above, everything you like about Fractal in those categories is present in the OG Helix's level of processing power in the FM3. I don't think that's a constraint at all.
I think this comparison needs the context that the architectures are completely different though. On the FM3, the amp (and iirc the delays) are on a dedicated core, and you can only have one reverb at a time and one amp at a time. The design considerations for what’s an acceptable amount of DSP usage are very different, and I’m sure that’s a factor.
EDIT to expand a little: if we are talking raw power, then any of these things are way more powerful than the “better” dedicated reverb units too, etc. But they have to consider how users will actually use them. If someone bought the then-flagship Helix (talking pre-Stadium here) and they can only run one reverb at a time and one amp at a time, and running the single reverb at full quality eats up half their DSP, they’ll be upset. The FM3 was sold as a lower powered unit, so those compromises, and some features of blocks being removed to keep things manageable, are more expected.
So, I’m sure the Helix CAN run way better reverb models using better techniques, but with massive trade-offs (and probably a customer service headache for Line 6). The Stadium shouldn’t require trade-offs that large, even if new models are still hungry enough that they won’t work in kitchen sink preset (in which case you just use the old ones) and Line 6 opts to not have a quality toggle for them.
