Are the machines that have this variable pre-set in production, or are these
dev systems?  Does this issue block the boot or does it "just" generate an
ugly error message?  From your perspective, should this block release of
this SRU, which has been delayed several times and will require another
round trip to Microsoft for signing to get this new patch included?

The current version of shim is known to have failures correctly booting to
e.g. fwupdate.efi (bug #1581299).  The pending SRU fixes this.
