Not to put too fine a point on it: The world has 35 years of experience with submodules. It's not rocket science. The committee just did what committees do.

And sure, "future extension" is nice. But not if the future arrives at an absolutely glacial pace and is technically more like the past.

This may be inevitable given the wide spread of the language, but it's also what's dooming the language to be the next COBOL. (On the upside, that means C++ folks can write themselves a yacht in retirement ;)

That is 35 years of different things tried, some that work better than others, some that are not compatible with others. Trying to figure out what is the best compromise while also making something that doesn't break existing code is hard when there are a lot of people who care.
