I may be completely misunderstanding the question, but if you put the flash zoom mode to 'Auto' The camera will set the flash zoom to match the lens focal length for you:

e.g. with a zoom lens fitted, the flash will change its zoom setting as you zoom the lens (the metering timer on the camera needs to be active i.e. half press on the shutter release button).

You didn't miss anything Dave. The lens should couple to the camera and send the appropriate focal length to the flash. I think the question was predicated on fill-flash techniques and manual operation of the flash-hence the need to set the proper focal length manually.

Yes, but even with both the camera and the flash in 'Manual' mode, you can still set 'auto-zoom' on the flash and it will still track the focal length of the lens.

i.e. You can have manual control of the flash light output whilst still having automatic control of the flash zoom.

Aside from actually asking the OP, this is just more speculation: He may have 'over-thought' the process. Done it a few times myself. One gets caught-up in some process and misses the obvious.

I've sure seen my share of that and, done my share of that.
