You can call it meaningless babble but in its simplest form

Yes, meaningless babble.
The phrase "antenna efficiency is 80%" says everything you need to know.
The phrase "antenna efficiency" is non-dimensional metadata
and to quote Mr. Clark
-quote-
Given that "efficiency" has been hijacked, the phrase above could as
easily relate to wind load.

The phrase "engine efficiency is 35%" says everything yoy need to know.
You assume that engine efficiency is only and always measured in terms
of energy efficiency.
Of course it is, that is basic physics and the definition.
Other things are other things and have qualifiers, especially if they use
the word "efficiency", otherwise it is just ignorant babble.

And if antennas is the topic to begin with, the phrase "efficiency is 80%"
says everything you need to know.
No "dimensional metadata" required.
Non-dimensional metadata (antennas) is provided as the topic and the
result contains non-dimensional metadata (efficiency) as well.
The phrase in question is "dimensional metadata" and now you are switching
the subject to "non-dimensional metadata".
As Mr.
Clark pointed out "antenna efficiency" is a potentially ambiguous
phrase. Such ambiguity can be eliminated by using dimensional metadata
e.g. antenna efficiency calculated as the ratio of power radiated to
input power.
The definition of antenna efficiency is the "ratio of power radiated to
input power", so stating that is redundant.

I suppose you argue with writers of recipes when they say "add 1 cup of milk"
saying they should say "pour milk into a measuring cup, that is a cup used for
measuring liquids, until the milk level, that is the level in the measuring
cup, reaches the mark on the measuring that denotes the meauring cup contains
1 fluid cup, in this case the milk, then pour the contents of the measuring
cup into..".
