Description

@avehtari @bgoodri Currently there is very little doc explaining the new default behavior for optimizing (and soon VB too). It's good to have the new warning messages and the doc for the new arguments, but they don't really explain anything about what actually happens when importance_resampling is TRUE or what the diagnostics mean. Anyone using optimization will now all of a sudden start seeing new warnings and different results, so it would be good to explain it somewhere. A vignette would be great, but even something more minimal for now would be ok.

Research direction

Start by reviewing the existing warning messages and documentation for the importance_resampling arguments and diagnostics. Determine what users of optimization and VB need explained about the changed default behavior, then document the behavior, warnings, diagnostics, and resulting changes in results in a suitable vignette or documentation page.
