Jekyll doesn't support includes with parameters

Even this is stated both in the Jekyll docs and Liquid docs... http://jekyllrb.com/docs/templates/#includes gives `{% include footer.html param=value variable-param=page.variable %}` as example - doesn't work. https://docs.shopify.com/themes/liquid-documentation/tags/theme-tags#multi-variable-snippet gives `{% include 'snippet', snippet_variable: 'this is it', snippet_variable_two: 'this is also it' %}` as example - doesn't work either. What kind of shitty software is this? What a unbelievable waste of time...
