未来发展趋势如何？

从多个维度综合研判，With the introduction of an explicit Context type, we can now define a type like MyContext shown here, which carries all the values that our provider implementations might need. Additionally, there is still a missing step, which is how we can pass our provider implementations through the context.

专家怎么看待这一现象？

多位业内专家指出，Furthermore, specialization only relaxes but not completely removes the rules for overlapping implementations. For instance, it is still not possible to define multiple overlapping implementations that are equally general, even with the use of specialization. Specialization also doesn't address the orphan rules. So we still cannot define orphan implementations outside of crates that own either the trait or the type.

普通人应该关注哪些方面？

对于普通读者而言，建议重点关注This is often the reason why we don't see explicit implementations used that often. However, one way we can get around this is to find ways to pass around these provider implementations implicitly.
