That's pretty bad, but I'd still file that under "too-hastily deprecating things before the new version is at parity". Not that it isn't a huge issue, but could it be a temporary issue? Is the newer one, in theory, on a good track for the long-term?
So while maybe they'll get it all fixed soon, based on their track record I'm pretty cynical and bet it's more likely in 2021 or 2022 they'll announce yet another overhaul of the rendering stack(s), probably unifying them back into one stack or something.
I guess everyone has different tolerances for what may technically be a 'temporary issue.' Yes, I have no doubt that all this engineering will lead to a better, more stable Unity, but for right now I actually have to somehow write real software and ship something to paying customers.
