When variable does not exist, output the variable tag - is this possible?

[netinlet]

I've been looking for a way to output the variable tag itself if it is not available when compiling the template. So if strictVariables=true throws an error and strictVariables=false renders an empty string when the variable does not exist, this option would not try to compile it and leave the liquid syntax in the output.

It's like a pre-compilation state. The goal is to have the developers create distinct sections/partials with their own variables that can be set. In new_page/index.liquid, they could render the different sections via {% render 'section1.liquid', color: 'blue' %} {% render 'section4.liquid', bob: 'is your uncle' %}. section1.liquid might have a variable {{ customer_first_name }} in addition to the scoped variable color: 'blue'. The new_page/index.liquid is intended to be a template itself which can be later compiled with the actual value of {{ customer_first_name }}.

I considered using a Proxy (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Proxy) to catch any missing variables and output {{ customer_first_name }} instead of losing the tag when it was compiled to an empty string. I think this could work unless there is a condition on {{ customer_first_name }}.

Is there anything in liquidjs that would allow skipping the compilation of undefined variables and outputting the code/variable/condition instead? Any alternative suggestions for solving the problem are greatly appreciated. It's not currently possible (without a significant amount of effort) to host all the sections/partials separately at the final render time. I'm building a tool to interact with a different app that expects a single liquid template input.

I figured this out. We can simply use {% raw %} {{ my_var | capitalize }} {% endraw %} to wrap the variables we don't want compiled. I missed the raw tag yesterday.
