Since all template instantiations must happen when you compile your program rather than in any libraries you're linking against, why would it matter?
AFAIK, there's no distinction between a library and a program in D, only modules and packages. How would it differentiate them? And I didn't see any documented guarantee for template instantiation optimization behavior.
The compiler would never try to share any template instantiations across them. They wouldn't even be involved with each other until the linker was run on them, so the compiler wouldn't even have the chance to try and share anything between them.
Nobody cares about intermediate files, only what gets into the final executable matters, and that is decided by the linker, and it will remove redundant template instances.
