Real-world impact of Denosie changes

I've reported some bugs with the newest Denoise changes, but just wanted to give an example of the real-world impact. Please leave in Discussions as an FYI post.

I'm a product photographer with a 2019 Intel MacBook Pro, Sequoia 15.5, AMD Radeon Pro 5300M 4GB, 16Gb RAM. I used this today with ACR 17.4.1 to process 22 CR3 RAW files from a Canon 90D. Yes its an older machine but it is currently supported by both Apple and Adobe and it does work ok. However...

I have arrived at applying Denoise at level 65 to these RAW files. So I opened all 22 RAWs. I select the first image and click Denoise. Wait 45 seconds for processing. Then due to an ACR bug (reported) I have to copy/paste the value 65 into the amount box.

Because of another bug (reported), ACR won't apply a custom amount to multiple images. So I move to the next image, click Denoise, paste 65 into the amount, and wait.

Lather, rinse, repeat. For 22 images. Waiting 45 seconds for each one to process. Not able to do anything else because I have to do this for EVERY SINGLE IMAGE in sequence.

As you can imagine, this workflow is frustrating and unworkable. I'm very close to just reverting to an older version of ACR so I can work efficiently.
