As of this commit, that layout doesn't exist yet, but I'm isolating the one-line changes to their own commit to try and keep your eyes from glazing over.

merge Function
-> Note: This page is about Terraform 0.12 and later. For Terraform 0.11 and earlier, see 0.11 Configuration Language: Interpolation Syntax.
merge takes an arbitrary number of maps or objects, and returns a single map
or object that contains a merged set of elements from all arguments.
If more than one given map or object defines the same key or attribute, then the one that is later in the argument sequence takes precedence. If the argument types do not match, the resulting type will be an object matching the type structure of the attributes after the merging rules have been applied.
Examples
> merge({a="b", c="d"}, {e="f", c="z"})
{
"a" = "b"
"c" = "z"
"e" = "f"
}
> merge({a="b"}, {a=[1,2], c="z"}, {d=3})
{
"a" = [
1,
2,
]
"c" = "z"
"d" = 3
}
