Details

My immediate use-case: I want my release binary to be able to use JS_SetGCZeal iff it's present in the js library I happen to have loaded.

There are probably other use-cases when embeddings need to safely feature-detect, such as when an application and a libmozjs.so are shipped separately, as is often the case with OS distro package schemes.  This feature could be expanded to those cases.

Features on my list for immediate test-ability:
  JSFEATURE_GC_ZEAL
  JSFEATURE_DEBUG
  JSFEATURE_THREADSAFE
  JSFEATURE_JIT
