I think that's ok. First, even if what you had requested to be applied to the
standard were there, it wouldn't apply here because the captures are not the
same. The first lambda captures 9 integers by value, the second captures 9
pointers. So how is this example relevant to the discussion?

Second, the most likely reason is that the compiler performed a constant
propagation in the first lambda, so the capture of 1 is actually zero and the
captures aren't actually captures, but are baked into the code. I think this
is an especially good idea and a very good reason to reject your proposal.
