It's going to be a bunch of work for me to unwrap all my dependent changes from my fix and encapsulation of kcontainer. Just finish your review of my work, I didn't ask you to play coding golf with this and I've been held up for a very long time in review. My performance is not evaluated based on how small a change you can eventually figure out how to make.

We can probably use git trick to simply revert the change #5389 included in #5406. I can facilitate the work. Are there any others PRs or branches affected by #5389?

[PDoakORNL]

I do not support this reversion.

I do not support this reversion.

This PR is left pending as it was. Will revise and clean up once your estimates get in.

Is this going anywhere?

[ye-luo]

@jtkrogel the changes is PR is still crucial to keep minimal code with mixed precision support.
I will follow up on this PR once @PDoakORNL finishes the dependent estimator.
