Looks relatively ready to go, code is easy to read and follows convention. Rather than using lambdas, you can reference the hyperparameter type's methods directly.

I reran the timed-out windows CI job, and make sure to finish the checklist. I think with a private CI run and @david-cortes-intel 's point addressed we can approve this.

Thank you for doing this. Its one of those hidden things for development that catches me from time to time. Nitpick would be to add a note in the PR description

[Vika-F]

Yes, I also have problems with it from time to time. Decided to put an end to those :)
I've updated the description.
