Selenium is calling geckodriver with the wrong parameter (webdriver-port was changed to port)

Linux
Selenium Version:
2.53.4 and 3.0.0-beta 1

Trying to run firefox in a selenium grid with marionette + a version compiled from the current source of geckodriver yelds an error in geckodriver telling that webdriver-port is an invalid argument. Looking at this commit mozilla/geckodriver@9e05d53, they changed the argument from 'webdriver-port' to 'port'

I have opened an issue there
mozilla/geckodriver#154

And the current answer from them is that this changed to be more in line with chromedriver. So I am opening here as well.
