Internal Review Topic

@daveabrock ... See how this is shaping up thus far.

• Follows your general blog post layout.
• Loosely follows your examples. However, I wasn't clear on why you had the types in the metadata for the passing parameters piece. You don't have the full implementation shown in your post, so I'm not sure how you use your metadata dictionary. I just keep the parameters and the name (for display) in the metadata and generate the options from it. Also, the naming might still be a bit dodgy ... I'm still working on that a bit.
• I'm not on the new bits yet. I tend to adopt preview releases starting with RC1 (for stability in what I'm documenting). This merely looks like 👀 it will work ... maybe 😆 ... or not 💥😆.

Hey Luke, sorry for the delay but this looks great! Yeah, a lot of it was early days when I wrote it so I didn't expand on a lot of topics. As such, if this deviates from the post (which is no big deal!) no worries about taking my name off the byline. 😀

It can stay as long as you like. This is based on your post. If you reach a point that you want off of this (and the CSS isolation topic), let me know (or submit a PR changing them to me). I think the MVP folks like to see this sort of thing, so I recommend leaving it at least until you confirm keeping that status.

Thanks so much - you're too good to me. I appreciate that.

I'll merge this shortly after making one more edit pass. I'll ask the PU to look later during RC1. They're all 🏃🏃🏃😅 right now working on 6.0 things.

@daveabrock ... Ok ... I think looks fine for a draft-ish preview doc. I'll come back to this at RC1 to make sure that it actually works 😄 (I hate when I put up docs that don't work. 🤦‍♂️) I'll also review+edit the whole thing at that time. I'll leave this here for a few hours to give you a chance to run a final 👁️ over it this morning and then merge it.

Looks good to me, @guardrex!
