By "adjust to" I meant living with the standard library's decisions without changing them. Compatibility with GNU syntax doesn't seem very important.

Well, I am the primary user of my command line applications as they are for my research. As the primary user they better be,

1. Easy to use

2. Have standardized syntax for flags across languages

3. Be easy to maintain

4. Be well documented so that I can use them a year or 5 years from now.

My applications often have complex syntax. For instance I work in frequent pattern mining, the basic syntax for some of my programs looks like:

  program [global options] -o <output> --support=<int> \
        <datatype> [data-type-options] <path-to-data>
        <algorithm> [algorithm-options]
        <filter-chains>
        <logging-and-serialization>
Being able to tightly control how the sub-commands chain together is important to me. Support for both short (-s) and long (--long) options make it easy to write both one off commands and self documenting commands in scripts and makefiles.

I write programs in more languages than just Go, and the programs in Go need to work the same way the programs in other languages work. That means GNU option syntax, which is the superior syntax for my needs in any case.
