I meant more like "not supported". You are correct that it is technically possible.

How useful is signal chaining even these days? 

While we could do something like this, I see more trouble ahead. How should we do when we put the static libs in a jmod? Should all static libraries have an "optional/required" flag attached to them? How do the user select if libjsig should be included or not?

I would argue that for the time being, it is better to set libjsig as `ONLY_EXPORTED`, and if/when we get back to revisit this, we can start compiling it always, and then we will also have a story on how to test it, how to handle it in jmods, etc, including perhaps a better idea on how important it is to have signal chaining for static builds.
