Are there any nearby plans to make more template instantiations (especially aggregate members) lazy in DMD?

Are there any specific obstacles against doing that or has it just not been prioritized?

Templates are never instantiated unless they're actually... well, instantiated. So, they're already lazy in that sense. The compiler isn't pre-emptive with them at all. What exactly about them do you want to be lazy that isn't?

Member functions of templated containers is my main focus.

Make them templates, that should solve the problem:

struct S(T) {
    void foo()() {
        compileerror;
    }
}
