templates don't exist in binaries.
Templates are like cookie molds, you use them to generate
lots of
(almost) identical cookies, but you never serve the mold to
the
customer. ;-)

I think the question is whether the instantiations of such
templates are removed. If the instance is used only to
initialize an enum, the function shouldn't stay in the binary.
Even if the function remains, I think the linker takes care of
removing unused functions.

I have a lot of code generation templates(only for code). I
want to make sure they don't hang around in the binary(even
strings they use) as there is no point and it is potentially
dangerous(security issues).
The linker will get rid of anything not needed. Marking things as
package (or more restrictive) will make sure they don't stay in
librarys when not used.
Ultimately, if you're worried about it, get the linker to print a
list of all functions, or check the assembly.
