It was explained to you that the op code is *valid* in the context of validating a block (so of course the block would not be rejected by older software). Why do you think it is called a NOP?
Sigh. That is what I always understood. But what does this mean:
The primary established mechanism for safe softforks is the reserved script NOPs (which will not be relayed or mined by unmodified software today)
We have tried again and again to explain but you simply refuse to even read what we post (and just keep on quoting one or another thing to keep on repeating your non-point) - so I'm done with trying to explain things to you (this is also off-topic anyway).
I would advise that you don't try to make suggestions about how Bitcoin should work when you don't even understand how it currently works (or how it used to work for that matter as relaying has been there since day one).
(I have read the code and have been a software engineer since the 1980's)
