No I couldn't push back to the main wiki... it's the intentional flow 
from gitlab:

$ git push ssh://git@source.puri.sm:/Librem5/developer.puri.sm.wiki.git
GitLab: You are not allowed to write to this project's wiki.
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

 From a wikipedia and like perspective that's not how it should be, but 
from the perspective of people used to github "pull requests" or gerrit 
review or whatever that's what feels like a normal flow.

But it implies someone has the job to maintain the wiki, collating and 
vetting "pull requests" to add stuff to the official wiki manually... if 
that's a job that should be, then it can be, if it's not a job that 
should be, it means making the main wiki editable by all if you want a 
wiki-style wiki.

It being based on git means you can use normal git-fu to snip vandalism 
out of the history or meddle with wording etc.
