But is it still acceptable to go to the dojo only to watch, or should you isolate yourself completely by not going at all?
As long as you don't sneeze on people, yes.
Many of the classes from which I have benefitted the most over the years have been classes I watched from the sidelines because of sickness or injury.
And to draw an example from outside the walls of the dojo, my son runs track and the coach's expectation is that injured team members will dress and travel with the team. Having seen how he feels about not being with his team when he has had to stay home because he was just too sick to be out of bed, the policy makes a lot of sense to me.
Hope this helps,
