Well-supported arrays of structs (as schemas) might be a satisfactory

Structs in ECMA-334 are value types, and consist of members that also
are value types. Would structs in future revisions of ECMA-262 share
these characteristics?
Is it fair to assume that there would end up being a more richer set
of primitives to select from when composing a struct than simply
"object", "boolean", "number", "string" and the like? Again, ECMA-334
defines the following:

Would something similar be envisioned for ECMA-262?
No, we did not envision adding more primitive types, type annotations,
conversion rules, and first-class struct declarations.
Something more like
const TA =
Array.newTypedArray(fixed_length,
Object.newStructType({x:"u32", y:"u32", z:"u32",
r:"u8", g:"u8", b:"u8", a:"u8"}));
let a = new TA(...);
... a[i].x ...
I'll note that with newStructType one could define a 128 bit quantity
for representing a complex number. That coupled with something like the
following proposal would enable a complete set of complex arithmetic
operators to be supported:
