Should this return true? There is no need to do windows sandbox setup on other platforms, so it is compete in a technical/literal sense. Less technically speaking, if a check on this condition leaks into linux/macos code, we probably don't want to follow the path more likely to to invoke run_elevated_setup

yeah I'll update this in a future PR. For now there is no leakage

This feels like we're piling tech debt on top of the "2 booleans" problem

agreed, will address in a future PR

nit: can we bump the non-windows variant to be first here?

+                        }


[non-blocking] I know this PR is not the source of the problem, but I feel like we're reaching a tipping point with the complexity in this function - we're iterating over the presets as if we're agnostic, but almost all of the logic in the function is targeted at specific variants. Seems like we'd be better off with a more declarative pattern.

could we move this function out of chatwidget into its own module?
