This is violating user expectation.

E.g.:

weights_untrimmed = sample.adjust(
    variables=weighting_variables,
    method="rake",
    weight_trimming_mean_ratio=0,
    transformations=auto_recodes,
)

By expectation violation I mean,

1. there isn’t anything in the docs that suggests that rake doesn’t support weight_trimming_mean_ratio or weight_trimming_percentile
2. there isn’t an error thrown when a value is passed to either weight_trimming_mean_ratio or weight_trimming_percentile suggesting that rake doesn’t support it.
3. this can result people thinking the weights are getting trimmed when they aren’t.
