It is not as dramatic as you make it sound.

In the most usual setup, the Git clones will _all_ have reflogs set up.  
So if you call

        $ git log -g origin/master

it will show the history of _this clone's_ origin/master.  IOW you will 
see exactly where a "forced update" reset your locally cached 
origin/master, and you will still have the formerly valid revision.

So no, there is no real harm done if you happened to "git fetch", even if 
nobody pushed the up-to-date versions again.

Oh, BTW, congratulations to switching away from Subversion just in time; 
it is much easier to recover with Git: just push a newer revision (and 
even if you should forget a revision, if somebody merges the former HEAD 
and pushes, all is well in Git land).

Ciao,
Dscho
