Interesting idea. I think this should probably reject all CHARACTER types too (so that it doesn't end up doing a byte-for-byte copy of descriptors).

So far as I know flang already generates inline assignment loops at optimization levels higher than -O0 (and as of recent changes this works for omp.private too). What exactly is the case where this is still useful? Does OpenMPOpt even run at O0?
