Patch 2/5, 3/5 and 4/5 don't change an existing format of a variable name and don't break anything.
The existing format consists of type, id and ctime. And it is not moditied by these patches.
Here is a variable name (and guid) of efi_pstore in curret linus-tree.

	ls /sys/firmware/efi/vars/
	dump-type0-1-1351113059-cfc8fc79-be2e-4ddc-97f0-9f98bfe298a0
	dump-type0-2-1351113059-cfc8fc79-be2e-4ddc-97f0-9f98bfe298a0
	dump-type0-3-1351113059-cfc8fc79-be2e-4ddc-97f0-9f98bfe298a0

	Variable Name: dump-type0-1-1351113059
	GUID: cfc8fc79-be2e-4ddc-97f0-9f98bfe298a0

On the other hand, patch 5/5 changes the format by adding sequence counter.
But efi_pstore_read is modied to work correctly in it.

	dump-type0-1-1-1351113059-cfc8fc79-be2e-4ddc-97f0-9f98bfe298a0

	Variable Name: dump-type0-1-1-1351113059
	GUID: cfc8fc79-be2e-4ddc-97f0-9f98bfe298a0

If I need to elaborate more, please feel free to ask me:)
I'm not sure if I understand your question completely.
