I think it is too early to think about this since it is just the first
public release. Also, as you have mentioned, there is the program_options
library already in Boost which tries to address the same problem though
in a different way.

I have answered this question in detail in the following two blog posts:
In a nutshell, program_options has the following main drawbacks:
- the use of strings to identify options (easy to misspell)
- the need to specify the option type every time its value is
retrieved (lack of type safety)
CLI addresses these problems by using a concise, special-purpose language
to capture the option specifications and by using functions with static
return types to access the option values.
