I think it's nice that this will soon be possible to do without adding Python as a dependency in your build system

> trivially

The article covers quite a few reasons why the way things are done without #embed are not quite as trivial as they seem.

I've been doing it for 20 years without any single issue, on fairly large files.

This proposal doesn't even allow to compress or encrypt the data.

And yet the issues in the article are real and non-trivial. Perhaps you just never hit them, or you have a high tolerance for non-trivial solutions.
