Certainly. It should not be done for public structs, which includes
basically everything that resides in header files. Modifying public structs
changes the ABI, so a module compiled for one CPython version would need to
be recompiled for the one that changes the structs *if* it uses them. I
don't think this change is worth that risk and hassle.
