I can't remember the exact wording on the proposed fix, it was on a fireside chat a few weeks back. I believe they said changing the ships will increase the timer until the match starts. I had not tested (and to this day, as the dev app was having steam problems for me, have not tested this) on the dev app, but if the proposed "fix" will allow you to change ships at the last second after all, it doesn't really seem like a real fix to me.
