I am a postdoc in mathematics, but have my degree in theoretical physics. My work is about mathematical structures motivated from quantum field theory and string theory. For more see my personal web on the nLab.

comment The physics community's take on noncommutative geometry
I just see that an earlier reference that highlights that the particle limit of the superstring's SCFT is a spectral triple are these lecture notes: Jürg Fröhlich, Krzysztof Gawędzki, "Conformal Field Theory and Geometry of Strings", extended lecture notes for lecture given at the Mathematical Quantum Theory Conference, Vancouver, Canada, August 4-8 arxiv.org/abs/hep-th/9310187 . They explicitly spell out a bunch of examples.

comment Why am I wrong about how to view gauge theory?
@drake: locally every gauge transformation is small (for a connected gauge group), so already quotienting out small gauge transformations destroys locality.

@Jia Yiyang, I see, right, I have edited the reply above to include now a point (5) that makes the relation to the construction that the OP considers more explicit.
