Why would I care unless I'm running a film recorder and my final output is
another piece of film?

Why? The transparency has to be scanned, there most likely has to be some
editing (in scanner driver or Photoshop) to produce a closer output referred
rendering based first on the display, then to some final output. Again, if
the final output is another chrome, what you want to do makes sense. If the
final is some printed piece, the chrome is just a single part of the imaging
process that is really immaterial now that you've scanned it and its in the
computer. What's the final output you want to match to the screen?
The chrome is no more accurate (colorimetrically) with respect to the scene
than any other part of the process required to produce some final output
that is supposed to represent the scene on a different media. IOW, you
always have to take the final output into consideration.
In theory, there's no reason you couldn't slap the chrome on a box with a
dimmer and match it (assuming the box could get to the necessary luminance
along with your display).

I don't believe it's been updated. It could use that considering where the
technology has gone since first proposed.
