Starting a maintenance script looks like this:

  rzl@deploy2002:~$ mwscript-k8s --comment="T341553" -- Version.php --wiki=enwiki

Any options for the mwscript-k8s tool, as described below, go before the --.

After the --, the first argument is the script name; everything else is passed to the script. This is the same as you're used to passing to mwscript.

Is that a limitation of Python's command line parsing?

I mean, the obvious way to do it from the viewpoint of usability is to take options after the first argument as belonging to the script.
