Yes, something like that. If you already have kexec-specific ways of
checking a version number then that's fine. Just make sure that, if the
EFI memory descriptor structure is extended in the future and more files
are exported for each descriptor, kexec-tools say "I don't know how to
build a data structure for from these files".
