I agree that it's more readable this way.

I only have a few comments:

I was comparing this new restart function to start and stop functions.
I see that restart() does not return a value if it's successful while
others return 1.
Its return value is not checked anywhere, so it may not be useful at
the moment. But I feel like it would be nice to make it look like
start()/stop(). What do you think?

There are two other places where ssl tests restart the node like
above. We can call $node->restart in those lines too.
