Now that the Git switchover is complete, this code freeze is lifted. SVN is now locked as far as core and WMF-deployed extensions go, so you can't commit there anymore. New commits for core and deployed extensions are welcome in Gerrit, see also Chad's message.
As for the reverts: I ended up reverting 103 revisions, but I had tagged many more. I was happy to see that dozens of revisions were reviewed overnight last night (PDT), otherwise the number of reverts would have been closer to 150. I am working on getting all the revisions I reverted resubmitted into Gerrit. I have finished doing this for all 39 reverted revisions in core, and I'll do extensions tonight or tomorrow. Each of these resubmitted revisions was tagged with a topic like resubmitted/123456, where 123456 is the original revision number in SVN.
