LGTM. Thanks, @gururaj1512, for working on this. It will be nice to finally wrap up the stats/base work.

Sorry, I didn't get it...!
Should we wrap these up?
What do you suggest to work on?

@gururaj1512 I meant to say "thank you for continuing to work on these refactorings, as it will be nice to finally get all of these refactorings over the finish line!". We've still got a few more of these refactorings to complete and which will allow us to finally migrate to the stats/strided namespace. 😅

[gururaj1512]

Got it...! 😅
Sure, I'll be on it @kgryte.
