check_array has several parameters that just enable a check on a property of the array, like ensure_2d, ensure_min_samples, ... They have no effect on the output array: they just have the effect to raise an error or not. They usually have the naming pattern ensure_xxx which I think is intuitive and explicit.

force_all_finite is another example of such behavior but doesn't follow the same naming pattern. I think it should be renamed ensure_all_finite.

• it would make the current set of params more consistent, intuitive and self explanatory.
• it would allow to add new params with the naming pattern force_xxx, that have a different behavior e.g. have an effect on the output array, without bringing confusion. This is for instance the case in FEA Add writeable parameter to check_array #29018 that proposes to add force_writeable.
