Historically, pyrotechnic or explosive applications for traditional thermites have been limited due to their relatively slow energy release rates. But because nanothermites are created from reactant particles with proximities approaching the atomic scale, energy release rates are far improved.[2]
MICs or Super-thermites are generally developed for military use, propellants, explosives, and pyrotechnics. Because of their highly increased reaction rate, nanosized thermitic materials are being researched by the U.S. military with the aim of developing new types of bombs that are several times more powerful than conventional explosives.[3] Nanoenergetic materials can store higher amounts of energy than conventional energetic materials and can be used in innovative ways to tailor the release of this energy.
the chemical formula beforehand which shows this to be quite a complex nano-thermite, augmented by Silicon and organic compounds in order to create this gas, that's why the paper studies 'gas generators'. This is not how high explosives work though, this reaction requires a primary thermite reaction, and a secondary reaction to produce the gas, wheras the primary reaction of high explosives is to transition to gas.
This is why they are so powerful and used as propellants in controlled demolition, and why there's no good reason to think it would be replaced with Thermite.

What exactly did I leave out?

My response covered the fact that nano materials do not necessarily require 'two stages' to produce gas (your
words), and that nano materials are superior to conventional explosives...which responds to your last sentence
about Thermite not being suitable in CD.
You're not bothering to look at specifics here, just quoting sections of papers you think might agree with you. They do not, controlled demolition charges work in a specific manner which none of these papers are discussing.
Let me try another tactic, could you please explain in reasonable the physical process which the nanomaterial or nanomaterial enhanced explosive outperforms a normal linear shaped charge? You don't seem to be interested in the actual physical reactions, just in quoting things which superficially agree with you. I would like to discuss the actual reality of these charges, how exactly would they work etc.
A fundamental component of any microsystem that uses nanothermites is a
suitable ignition source. One useful characteristic of a versatile ignition source is the
ability to trigger it using CMOS circuits, thus opening the possibility for unique
applications by use of simultaneous, or sequential, triggering of the events with great
precision.
Based on these observations, we conclude that the red layer of the red/gray chips we have discovered in
the WTC dust is active, unreacted thermitic material, incorporating nanotechnology, and is a highly energetic
pyrotechnic or explosive material.

However, the area under the graph is the total heat emitted, and when you are trying to melt steel it is this that is more important than reaction rate.
