When data gets shared among multiple parties it is important that a

Antenna efficiency can be measured in different ways so the phrase
"antenna efficiency is 20%" can mean different things to different
people. All it takes is one person to ask how antenna efficiency is
calculated and it will become evident that context of "antenna
efficiency is 20%" does not provide all the information required.

Sure it does. Antenna efficiency is only calculated one way,
so there is no need to add extra "metadata".

Funny thing, when working parabolic antennas antenna efficiency and
aperture efficiency are used interchangeably.
