Unity isn't one tool, however. DOTS does a lot of amazing things, but most of its job is done on the CPU. and issues here sound like GPU laden issues. DOTS could certainly do a better job talking to HDRP but DOTS has always been talked about as "in alpha/beta" until mid 2022. those integrations and polish are the exact reasons why, and I argue that it came out of beta much too early as is.
I think many of the issues with Unity are caused by them not using their own product. If they are never going to make games, then they need to listen to their customers far more closely.
Even if the user insists on being a little bit weird. Perhaps especially so.
We like to chase the most difficult customers. It forces us to have the best products.
