Describe the bug 🐞

Using getp with mixed scalar and array variables leads to a Vector{Any} of both scalar and vector values, while getu(::BatchedInterface) scalarizes the array variables.

Expected behavior

I think they should behave the same.

Minimal Reproducible Example 👇

Considering

using ModelingToolkit
import ModelingToolkit.t_nounits as t
import ModelingToolkit.D_nounits as D
using SymbolicIndexingInterface

function mwe()
    @parameters p1 = 0.5 [tunable = true] (p23[1:2] = [1, 3.0]) [tunable = true] p4 = 3 [tunable = false] y0 = 1.2 [tunable = false]
    @variables x(t) = 2 y(t) = y0

    eqs = [
        D(x) ~ p1 * x - p23[1] * x * y
        D(y) ~ -p23[2] * y + p4 * x * y
    ]
    sys = ODESystem(eqs, t, tspan=(0, 3.0), name=:sys)

    structural_simplify(sys)
end

sys = mwe()

ref_prob = ODEProblem(sys, [], (0., 1,), [sys.p1=>1.5])

tp = [sys.p23, sys.p1]

we get

julia> getp(ref_prob, tp)(ref_prob)
2-element Vector{Any}:
  [1.0, 3.0]
 1.5

and

julia> getu(BatchedInterface((ref_prob,tp)))(ref_prob)
3-element Vector{Float64}:
 1.0
 3.0
 1.5
