not sure how this would be much of a benefit. Is the idea that because of the use of PUT instead of PATCH the reason for changing it despite their being no real difference?

Since the update mask is no longer used I thought it made sense to use default values when possible, that is the reason for the changes on ln 26 & 27. Update mask is no longer being used as it does not support updating the properties field.
