In general, I also think that except for describing the available values in each of the fields the rest should go on another page. Maybe adding a link to a blog using the hybrid mode and explaining why it can be beneficial in some cases? cc @omnomagonz @rberrelleza @RinkiyaKeDad

I'm open to having a blog for this! It could be a nice idea to get visibility for this feature. But my concern is we still need something in the docs which explains this. For example, someone looking to learn more about this feature when implementing might not stumble on the blog, but they will definitely go to the docs to search about this.

Now we could link the blog from the docs, but I haven't seen a lot of technical docs do that and I think that's because the target audience and the tone for blogs is usually different from docs. If we feel this feature is relevant enough, maybe we could have a separate page in the docs?

I opened #450 since I thought it might be cleaner than altering this one.

Please let me know if anyone prefers to consolidate into this PR and/or feel free to comment on the new PR

Closing this one in favor of #450 then, let's continue there.
Sorry for any noisy notifications (deleted prev comment since I had a cached outdated state of this PR…).
