Support generic spec inside facet

[kanitw]

The semantic of facet would not be what people expect.

(I'll provide more example soon)

I feel having a repeat could be a useful thing to have inside a facet. Admittedly, you could do the inverse: a repeat of a facet. Anyway, I would like to see some examples of how the output is unexpected and an argument that there aren't cases where you would want arbitrary composition.

I think Repeat of facet is way better visualization than facet of repeat as the latter would be extremely confusing for readers (non-creator).

A while ago, I had created a facet of concat plots to see two different views of each facet.

I think longer term we certainly should support all of them.

However, currently there are some amount of corner cases that we do not support well.

• Support facet of concat of facet_column #2759 -- facet of concat of facet_column (I haven't test if it works, but suspect that it probably won't.)

• Correctly Cross Nested Facet #2775 -- Cross Nested Facet

• Incorrect axes merging rule for facet of facet  #2761

So instead of delaying our release more, I'd rather support less things, but do them well.

In #2977, we now limit facet to only have layer or unit inside. I'm changing this issue to become "Support generic spec inside facet" and move it out from 2.0 milestone.

• Support faceted concat Facet of concat does not work #5261

Here is a cool example of facet concat use case: https://observablehq.com/@john-guerra/california-covid-19-disparities-stacked-bars/2
