Hah, that was me!! Sorry I made it sound ominous, I thought the route looked excellent, I was just out of sorts, inconveniently emotional. So delighted to see you guys made it (kinda making me wish I continued), thx for posting
Beta for other potential soloists: if you aim for Kennedy Peak, you can walk between it and its subpeak (looks round on a topo map, but there are two spires). Then drop down to a saddle (my intended campsite) and head SE from there on crevasse-free snowfields to the ridge. Though this involves a bit more elevation waste, it avoids just about all glacier travel on approach, and the glacier you do get on (around N side of Kennedy Peak) is pretty tame. I would probe though, you can see minor crevassing in late season satellite imagery. Tracks below show that and also a misguided attempt in 2019. Third time's the charm for me?

Another advantage of this approach is that you'll spot the elusive PNW parrot.
