Presumably you mean "the main intent for *adding an option to --extcap-verson*" - there *already existed* a --extcap-version argument, which told the extcap program to report its version:
$ /Applications/Wireshark.app/Contents/MacOS/Wireshark --version
Wireshark 2.6.1 (v2.6.1-0-g860a78b3)
...
$ /Applications/Wireshark.app/Contents/MacOS/extcap/randpktdump --extcap-version
extcap {version=0.1.0}{help=file:///usr/local/share/wireshark/randpktdump.html}
