I can't find anything that specifically says this, but I'm pretty sure whatever voltage you run to the solenoid breakout, it sends the same voltage out to the solenoid, whether it's 12V or 24V, correct?
Your supporting statements are correct, but your main conclusion is not.

It is absolutely true that a single solenoid breakout can only supply a single voltage to ALL of its 8 channels.

However, you are not forced to only use all 12V or all 24V. Spike Relays are still legal and can control 12V solenoids (not 24V). Also, the 2010 image supports two solenoid breakouts, which may run at separate voltages if desired. "Mixed Mode" is well supported.
