Based on Robert's code, isn't this false, with it being a feature of super
and not send?

No. Robert's code with super certainly demonstrated that super will propagate a block but that is entirely beside the point because send doesn't use super to invoke the named method. I really don't understand why Robert said:
Automatic propagation of the block is not a feature of #send but a feature of "super":
Internally #send is written to propagate any block to the named method and that should be documented.

My point was, that _automatic_ propagation (i.e. propagation without
the user needing to do something) is only done by "super" (please see
the example). All other delegating mechanisms (i.e. directly calling
a method, invoking #send) do need to explicit propagate the block.
And #send likely does so internally as well - although I tend to view
#send less as a method but rather as a language feature of Ruby's
reflection capabilities.
Internally #send is written to propagate any block to the named method and that should be documented.
Yes, of course. Method #send without block propagation would render
it pretty much useless since any method in Ruby can use a block.
Kind regards
