Feedback on "on-discourse" javascript for setting up custom JS for each page?

The right way is to add the code using a plugin

Not true.

If you are not modifying the API (e.g. using 100% javascript) there is no need to use a Plugin which are more cumbersome to deploy and switch out.

If all you are doing is modifying or adding some JavaScript a Theme Component should suffice.
