One thing to consider is that some provisions (and overall clarity) protect users of your code. The best example is including patent grants in the license terms (like those in Apache v2 and GPLv3) that may not be covered in that one liner. There's also provisions (or implications thereof) that can protect the community around your project, like how the Apache license includes a clause that specifies that contributions back to the project are assumed to be under the Apache license by default.
