I personally dislike to believe on that.
I see. Is your concern that changes to the EFI spec won't be backwards-compatible, or that Parted will not be careful enough in its handling of the part of the header it doesn't understand? > > In this case, the EFI spec shows a table of the fields in the header, > > and it includes as the last "field" all the remaining space in the > > block.

No, I mean that Parted cannot check the CRC of an OpenSolaris partition because Parted uses a constant rather than the value of HeaderSize in the disk label to determine how many bytes to compute the CRC over.
