How do modern washers/dryers not have a real child lock?

We just replaced our ~15-year-old GE washer/dryer with a new Electrolux set (ELFW7738AA and ELFE773CAA) and never thought to check for a child lock; we assumed it would be standard. To be clear, I’m not talking about the automatic door lock during a wash cycle, or the “Control Lock” that prevents operation between cycles. I mean a true child lock that disables all controls while the machine continues running. Our old GE did exactly this: long-press the Signal button during a cycle and the entire panel was locked until deliberately unlocked. On the Electrolux set, once a cycle is running our toddler can still pause, cancel, or power the machine off. Our laundry area is central to the house, so this is already happening regularly. I’ve gone through the manuals, tested the documented lock behaviour, and asked the sales rep we bought them from. So far, it appears there’s no in-cycle control lock. Am I missing something, or is this functionality genuinely absent on some modern machines? Edit: I received confirmation from Electrolux that these models don’t have dedicated child lock controls.
