@i3arnon, sorry for the delay.

All the changes look good but there appear to be a few merge conflicts present. Could you resolve those? This should be mergeable once that is complete.

Tagged as 'needs more info' to capture that the conflicts need to be resolved.

[tannergooding]

@i3arnon are you still working on this?

No particular rush, just wanted to ensure that was the case since many people took a break over the holidays. There are still pending comments above that would need to be resolved.

[i3arnon]

@tannergooding I solved the conflicts. Sorry for the delay..

[tannergooding]

Sorry for the delay. This was blocked/delayed while we worked through various other issues involving generic math and prepping it for .NET 7.

All those issues have now been resolved and we can merge this.

There are, unfortunately, some more conflicts. These are a side effect of other PRs also being unblocked and the interfaces now being "implicitly", rather than "explicitly", implemented.

If you're otherwise busy, I can push up fixes for the conflicts here.

[i3arnon]

@tannergooding I fixed the conflicts.
