TS readonly Convex values

I've run into the issue a few times of having a readonly value, like

readonly number[]

readonly number[]

, which I'd like to pass in as an argument to something like

db.insert

db.insert

for a table whose schema is

v.array(v.number())

v.array(v.number())

. TypeScript sees

readonly number[]

readonly number[]

as unassignable to the type

number[]

number[]

, and gives me a type error.

I wonder how the DX might be improved here? Would it be too ungainly to have

v.array<T>

v.array<T>

produce the type

readonly T[] | T[]

readonly T[] | T[]

(same with

v.object

v.object

)?

For what it's worth, I just about never use

readonly

readonly

in my own code (and am not too familiar even with what it purports to guarantee, or not)—these examples have come from types in third-party libraries.
