... and now requires double alignment ... did you fix its typalign?
We could conceivably dodge the alignment increase by splitting the 64-bit
field into two 32-bit fields, one for base privileges and one for grant
options. That'd be rather invasive, so unless it leads to pleasant
improvements in readability (which it might, perhaps) I wouldn't advocate
for it.
