It does, I'll try to find a public example.

For the line numbers (for code within the page) see
https://moinmo.in/HelpOnFormatting#SyntaxHighlighting
https://wiki.python.org/moin/HelpOnFormatting#SyntaxHighlighting

However the feature is advertised in the docs, but at least in
 one moinmoin instance I could not use it - maybe a small defect.
I'll inquire.

That is also my current favourite, and my company Intevation would
pick up the costs for now.

Should I present this to our development or users list as proposal to reach
more people?

We could, though Moinmoin as software package is more widespread than SF's 
Allura. For the markup Markdown probably has more pages than MoinMoin's 
markup, but the interesting part for the migration is in the special 
features, so I'd say that having this in the moinmoin structure is more 
future proof. So our ticket should have been to improve the existing tools to 
export from moinmoin to other markups and structures.
