The key thing, and possibly the next thing that will 'happen' to indicate which way the wind is blowing, will be whether PRH publish OWH or not.
They haven't had to do anything at all so far, other than a single statement defending their due diligence, and announcing the postponement of OWH, way back last July, but they will have to show their hand at some point over the next few months. Whether they publish it or not, it's a declaration either way.
Not that them not publishing would necessarily indicate an end to SW's writing career, of course. Perfectly possible for her to take some kind of partial, self-excusing mea culpa (The Salt Path: The True Story) to another publisher.
(Or even to take OWH elsewhere depending on the terms on which PRH chose not to publish, what's in her contract etc.)
It would be an interesting problem for her agent, to oversee her transition from the wispy, unworldly, Vogon poetry-spinning, all-round good egg 'Raynor Winn' to whatever she might choose to present herself as without that cosy, carefully-scripted persona.
I mean, given what seems to be her USP as a writer, across fiction and purported memoir, the 'pure soul' shtick -- if all possibility of that were removed, and that persona thoroughly exploded, could she still even write?
Her two sequels to TSP were written in the position of knowing she had a devoted readership who were delighted to hear more from her about someone they believed they knew, just as all her press and book events have involved 'soft', sympathetic questions which are essentially aimed at prompting her usual script for an existing fan base.
How would she deal with writing for a readership predisposed to doubt and criticise?
