Is it possible to remove the filter from 4.8 text widget?

We now have a new filter widget_text_content introduced in 4.8 ^src, with the following default callbacks:

add_filter( 'widget_text_content', 'capital_P_dangit', 11 );
add_filter( 'widget_text_content', 'wptexturize'          );
add_filter( 'widget_text_content', 'convert_smilies',  20 );
add_filter( 'widget_text_content', 'wpautop'              );

that are applied if the filter settings, for the widget instance, is set to 'content'.

When you remove the filter settings by hand from the wp_options table, it seems to be reset during the update method ^src.

See trac ticket #35243 for more info.
