Wow. I had to read that statement a couple of time to understand exactly what you had inferred. That’s ... really neat.
It flowed just fine for me because I pronounce it S-Q-L in my head as well. I don't know why saying SEQUAL has always felt unnatural to me. Probably because I came across it independently and learned about it by myself instead of having someone else introduce it to me as SEQUAL before seeing the acronym.
