The EVAL-CORR (Assign corresponding subfields) documentation suggests
that "When the source and target data structures or corresponding source
and target subfields which are both data structures are defined the same
way with LIKEDS or LIKEREC, that is, both data structures are defined
like the same data structure, the compiler will optimize the assignment
and assign the data structure as a whole, and not as a series of
individual subfield assignments." I do not think that operation would help.

Ah. So EVAL-CORR is the same as EVAL when the data structures are the
same? Lovely. So instead of giving the programmer the choice of how
to assign like-defined data structures, RPG forces the programmer to
do the subfield assignment the "long way round". Or deliberately
mangle one of the data structures so that they are not like-defined.

Instead of complaining or badmouthing, I will say again: Just avoid
defining varying subfields.
