There's substantial number of different improvements since "0.3.0" which is used now. I guess it'd not only generally improve execution, but also might enable simplification of some current helpers introduced in the code.
Likely will require upgrade of secp256k1 = { git = "https://github.com/geometryresearch/ark-secp256k1.git" } too. On the other hand chances are ~0.4.0 provide stuff that is provided by that crate now.
