why did we need this again? does this double-process?  i thought we were going
to split these files into

i18n_template_no_process.js
i18n_template_process.js

and include them both here, and then make a

i18n_template.js

that just did

<include src="i18n_template_no_process.js">
<include src="i18n_template_process.js">

for those still using GRIT

Removing this causes the following error
Uncaught ReferenceError: i18nTemplate is not defined
    at crisper.js:593

So it is not about avoiding double-process, it's about including this file. In
vulcanized mode this is not included otherwise because the following line is
ignored
https://cs.chromium.org/chromium/src/ui/webui/resources/js/i18n_template.js?q...

i thought we were going to split these files into
