What constitutes a publishable paper depends on the subfield and journal/conference.

There are many computer science papers discussing the usability, implementation, application of tech ologies.

Definitely. And I wouldn't be surprised to see more methods papers from movies going forward.

If you can write something useful about the results or the things you discovered or developed in the process, sure. (Not in every venue of course, but in many)

I don't know enough about the specific subfields involved here to guess where and if this specific example would likely pass.

There are basically no barriers to "publication" on arXiv.
