Are there precedences of combining verbose and version options in other 
programs?

PyPy just outputs sys.version for the --version option.

$ pypy -V
Python 2.7.10 (5.4.1+dfsg-1~ppa1~ubuntu16.04, Sep 06 2016, 23:11:39)
[PyPy 5.4.1 with GCC 5.4.0 20160609]

I think it would not be large breakage if new releases of CPython become 
outputting extended version information by default.
