Originally the idea behind only supporting double was as @sethah posted
above - there could be some issues with handling of int casting etc. As
mentioned originally, we did consider "always cast to double". The only issue
with it is the potential for surprising users who may expect the type of the
input column to be maintained in the imputation.
Having said that I would be broadly ok with just appending a double output
column, provided we update the docstrings / guide to make things very clear.
