Feedback "High" Filtering for shadows in HDRP

I'm a fan of the properties exposed to you when using high filtering.
A property to control shadow softness is a must, but it feels like high filtering is more problematic than medium filtering. More hidden issues, and sometimes medium looks better.
Although when it works, it's much better.

Any opinions/thoughts on it? What can be improved? Or any problems you noticed using high filtering?

I tried it in a test project and right away found 2 bugs. Reported both of them.
Although to be fair, one of the bug reports I'm not positive is a bug.

 

The default sample counts are set unnecessary high, atleast for most use cases.
I went down from 24 to 4 blocker samples and from 16 to 2 filter samples without really compromising the visual quality.

The only issue I had with them was when I turned off TAA, which resulted in super noisy filtering.
So TAA is a must have if you want to use them.
