  Yes, that is true, but the Coq community has been pushing Coq far beyond its origins in CTT & derivational-type theory for merely functional programming.  Coq is increasingly setting its sights on the wild-west worlds of C and machine code:

I bring up Z-notation as a relatively-widely-known example of logic-based system-specification language to the Ada community because I find it extraordinarily odd that on one hand Ada seeks to be the safety language for critical systems (OMG! we're all gonna die without Ada), but then on the other hand defines Ada's language semantics in English prose that compiler vendors cannot take as direct input into their compiler implementations.  (And then the Ada community argues for decades on end here at comp.lang.ada whether this darned compiler versus my exemplary program versus the ARM/AARM got it wrong regarding some unexpected Ada behavior, when a nontrivial fraction of these debates have the unverified-incompleteness* of or the ambiguity of English prose in the ARM as the root cause.)

* Oops, the ARG forgot to handle that case, which might have been easily caught under formal-methods analysis of a non-prose specification of Ada's semantics.

Speaking of SPARK, here is SPARK-esque analogue for a subset of C++:

Btw, Luke Guest, your envisioned out-with-the-cruft-&-in-with-the-well-oiled-machine Ada for the 21st century would not have its language specification in English prose.
