No we're getting into my main territory, language.
The verbing of nouns is foundational to English and generally happens when there is a need for a linguistic shortcut. It's why I can look out the window right now, notice that it's raining, and not feel a little hiccup in the parts of my brain that parse language. So, pedants be damned, it's a feature and not a flaw.
And that's why 'Xandering' is going nowhere, IMO. But then, 'Jacquaying' also went nowhere. I had never heard or read the term before, and I'm the kind of person who has thousands of posts on forums like this. For a word or new usage of a word to make it, there has to be a hole that needs filling, enough to create popular acceptance, and I don't see it here. Is either new term more economical than simply saying 'non-linear'? No. Do either tease out some sort of significant distinction that 'non-linear' lacks? Not that I can tell. Is either such an obvious allusion that it immediately ignites a spark of cultural recognition amongst the TTRPG community, so that now we know exactly what you mean? Afraid not.
As Snarf adroitly pointed out some pages ago, Justin Alexander is essentially trying to "make 'fetch' happen." Twice. That's not how language works unless you can get yourself a much bigger audience than Justin Alexander commands. Which is why what we have here is a tempest in a teapot (thanks, Cicero).
