I will just add that if you have heterogeneous types, you might want to
look at the ColumnTransformer:
https://scikit-learn.org/stable/auto_examples/compose/plot_column_transformer_mixed_types.html
You might want to apply some scaling (would not be relevant for tree
thought) and encode categories
I am +1 for this change.
I agree that users will accommodate the syntax sooner or later.

If you have datasets with many categorical features, and perhaps many
categories, the tools in sklearn are quite limited,
but there are alternative implementations of boosted trees that are
designed with categorical features in mind. Take a look
at catboost [1], which has an sklearn-compatible API.

Thanks, Guillaume.
Column transformer looks pretty neat. I've also heard though, this pipeline
can be tedious to set up? Specifying what you want for every feature is a
pain.
Jaiver,
Actually, you guessed right. My real data has only one numerical
variable, looks more like this:
