You appear to have significantly overestimated any fixes to the ZwiftPower site, I’m still finding about 1 race in 3 is failing to have some or all of its ‘fit files’ processed.
Most recently yesterday afternoon’s Road to Sky ride where no-one in Category A, B, or C has had their data properly reported:
ZwiftPower Event ID=1946028
As for a “constructive” discussion, I think most would agree that your bullet point glibly saying you’re not asking for a “blue sky wishlist for a faster, stronger, able-to-leap-tall-buildings ZwiftPower” is the pretty much the definition of non-constructive since long-suffering users would almost universally accept a site that simply works in the most basic sense by processing all ride data, processing that data correctly, and doing so in a somewhat timely manner. We’re far too realistic to be expecting anything else or better and I imagine many are annoyed at even reading such a barbed point, I recommend you remove it!
