I'd kill for a peek into the parallel universe where it was permanent standard time that was likely to get adopted and see how much effort went into researching the ill effects of that choice to convince people with enough FUD to keep daylight time switching going.
Here's the thing: If you're a proponent of permanent standard time, you should be in favour of turning off the switching no matter what. Even if it means daylight time. Because you know what? Your local time zone is changeable. You can lobby to change it. If permanent DST really results in the entire country turning into sleep deprived zombies having spontaneous heart attacks as they arrive at work and crashing into children going to school, then there'll be pressure to change it -- but we will have at least already started the process of eliminating the worse thing: changing twice a year.
