No, it's saying that Bladesinger is a better term than Fighter-Wizard.
It's saying that THREADCRAPPING WORD is a better term than Warrior-Mage.
It's saying that Bard or Skald are better terms than Warrior-Poet.
It's saying that Swashbuckler is a better term than Fighter-Rogue.
Any term that sounds like a 2E multiclass character is inferior to a single word that encompasses the whole of the character.
The one disconnect you seem to be having is that you seem to think the G-word means something in the english language just like all of the other words.
It doesn't. You have to explain what it means, and then possibly explain the origin of the word,
then, more than not, have to explain what in the hell Githyanki and Githzerai are. Therefor, it's not a good word to use. A good word to use is immediately recognizable to those outside of the culture so that it can be introduced to newcomers relatively easily. If this can't be done, then it's "jargon" and should not be used in any official capacity.
As a culture we shouldn't be in the practice of alienating newcomers with extremely arcane terminology.
By the by:
Bladesinger
is not a good term for a Fighter/Wizard, maybe a Fighter/Bard, but that's about it.
Skald
is a good term for Warrior-Poet, because, well, "Warrior-Poet" is the definition of that word.
Swashbuckler evokes "romanticized pirate" more than a Fighter/Rogue combo, so it too, isn't a very good replacement.
