Very interesting! I had been planning to look up the episode to see for sure, but I forgot to do it.

The pronunciation they ended up going with rolls off the tongue a little easier for me, so maybe that was the reason. I don't remember the first DS9 episode to mention it, but I remembered it being in 2x21 The Wire, so I looked that up. https://www.st-minutiae.com/resources/scripts/441.txt By this point it had been changed to the more common version.
