but because the SvUVs are aliased for SvRVs, it also assumes that the value in the SvUV is an SV* and clones that also.

If Perl assume all UVs were really pointers to SVs, it would crash left and right. Either the scalar is a reference (ROK) or a UV (IOK + IsUV). What you describe will only happen for the former. I didn't suggest using a reference.
