Not that I know. Sexps come back to the OMTool (from Martin Marietta,
Inc.) more than 15 years ago. IIRC, it was not written in lisp but
in Smalltalk. Rumbaugh then came to Rational. The sexprs were only
used as an internal data format.

The point is that it's a damn good idea to use sexprs, a "competitive
advantage".

Also you can see it as Greenspun Tenth Law in action...
