While the original issue is right, there was something missing, I am not sure this is the best approach. I'd say that doing both things in the same command is relatively unlikely, they are very different things for different purposes. You want the build-order for CI mostly, and the HTML is basically for human-readable purposes.

I think that the future UI in Conan 2.0 will totally separate these concepts as different subcommands or something similar.

So breaking users for the value of this functionality... I am not fully convinced. I see @lasote approved, but just in case, wdyt?

Why not prevent both options together? I mean, raising an error. I now, it's a breaking change, but for now we don't execute both commands together, but also we don't provide any message.

If right now using both options doesn't produce the intended output it is a bug. But it can be considered a bug in either direction: it is a bug to allow those arguments without raising, or it is a bug to not produce the output. Having a look at the behavior of the function and how little those functionalities are correlated, I'd say go with the former, and thus avoid breaking the conan_api (as a side effect, if we need to break it, we can break it, but the benefit should be clear).

@memsharded is right. The gain of this addition doesn't worth the possibility of breaking a CI from a user, even if the conan_api is not stable. I would say we should error for that combination of arguments.
