Set input_html values application-wide for simple_form

Question

I've upgraded simple_form from 2.1.0 to 3.0.3 (yes, still pretty old) and Rails from 3.2.22 to 4.2.10, and it seems like as a result, I've lost it setting for textarea elements associated with a text column a default of cols being 40, and rows being 20. Now it doesn't seem to set any values for cols and rows.

Is it possible to configure simple_form to set cols and rows for textarea for text application-wide? Or do I have to set something like

<%= f.input :message, input_html: {cols: 40, rows: 20} %>

for every input in the application?

I tried searching the simple_form github repo, and there's only three mentions of input_html in their wiki, none of which addressed this issue.

Simple Form offers an easy way to change the default behaviour (v3.0.3) by redefining existing Simple Form inputs. This is done by creating a new class with the same name. For instance, if you want to set default rows and cols, you can do:

# app/inputs/text_input.rb
class TextInput < SimpleForm::Inputs::TextInput
  def input
    input_html_options[:cols] ||= 40
    input_html_options[:rows] ||= 20
    super
  end
end
