Stupid request? I've been the customer requesting no code other than Ladder. Because I'm stupid? No...because I don't want to be the one on call 24/7 to support the thing. "Just hire qualified technicians"...because they're just swarming the streets in packs looking for jobs?
All absolutes are stupid, I stand by it and feel sorry you're like that because in a way it shows your lack of experience with Rockwell stuff and possible applications with those controllers.
Also, because Rockwell doesn't allow certain instructions in Ladder, doing so increases the likelihood of issues being brought in or code that technicians that you drag off the street won't understand in a million years either...
If you instead told me that you want the majority of your code to be ladder and provide examples of where other languages are to be used provided they're encapsulated and tested independently, I'd say that we're pretty much alike.
Be careful where you blindly fling "stupid".
Be careful where you blindly throw absolutes...
There are many reasons someone might not want "advanced" languages in their PLC and being stupid is almost certainly NOT it.
And those reasons are generally absolute ******** from neckbeards who are affraid of change... there are indeed reasons to stick to Ladder and I support them in pretty much all platforms. But there are also a magnitude of problems where ladder is definitely the worst possible language to use which make the code more obscure when it would be simpler in ST or even FBD.
And this is coming from someone that won't accept most SFC sequences because of the risk of resetting them at the wrong place... but Ladder isn't the right language for a fair few things in automation.
But hey, if screwing in nails has worked for you, keep at it.
P.S.: Sorry if I'm being blunt, but being a fundamentalist irks me to an extreme.
