If your point is that BYOK is a useless acronym since it has the same number* of syllables, I disagree. Acronyms aren't just for reducing syllable count; they also reduce visual clutter and are easier to read for people who scan text.
My brother from another mother, I thought I was the only one left who distinguishes much from many. (I wish I didn't know that it's technically an initialism not an acronym...)
"Bring your own key" has the same amount of syllables as "BYOK"
