I think that validation function here is to speed up the process in case
of unsupported offloading patterns. It saves time for all the not needed
memory allocations and copies. With this change we will construct all the
patterns and only in the end will realize that we don't need them as the
flow can not be offloaded.
Best regards, Ilya Maximets.
