@PatStLouis @jamshale -- please take a look when you can. @gmulhearn -- @jamshale is on vacation today, so won't see this until next week.

Thanks for looking into this, its been on my radar for some time.

[jamshale]

This looks good to me. Removes unnecessary complexity. I'll give @PatStLouis a chance to review as he did the MultikeyManager implementation.

[jamshale]

I'm going to wait to merge this. We're really trying to get the Kanon profile stuff in and I don't want to cause any potential merge conflicts withit.

[gmulhearn]

@jamshale sounds good! let me know when it's ready and i'll rebase this branch

[jamshale]

@gmulhearn Can you please update this with main now and we will get it merged? Thx.

[jamshale]

@gmulhearn Sorry. I merged another PR and github isn't letting me update the branch. Could you do it one more time please?
