I have no problems with aggregate constant initializers for global
variables. We can support the syntax without allowing them through the
verifier inside of function bodies.

My real problem lies with operands which are aggregate constant values.

As I said in my followup though, this problem is strictly smaller than the
constantexpr problem, and may not be worth addressing separately.
