If voting is what is required to get functionality back then consider this my vote for yes, please make fixing the Chrome extension a priority. The missing comments section has completely destroyed my workflow.
I'm not sure about Chrome itself, but I use Vivaldi, a Chrome based browser, and I was able to restore version 6.13.2 as long as I also keep the new version installed but disabled to prevent auto updating. If you don't have the new version installed as well, it will update and overwrite the older, better extension.
There does not seem to be any problems running the older version in Vivaldi either. Everything functions as it always has. It's likely only going to last until the next Vivaldi update when they catch up to Chrome and add whatever it was which broke the extension in the first place.
