Jack, you may have some valid concerns. If you wanted to use the plainer, published 'VOR or GPS' 13L approach plate, and plain 'VOR' FMS coding in order to avoid what you've described, and have absolutely ZERO vertical FMS guidance from 800ft, or lateral guidance around the curve, what's stopping you?
It's a genuine question, I'm not taking a position.
The guidance on how to do the 'pure VOR' is in CCI pages and the chart is there if you prefer it. Pure VOR is messy though, and pilots have had safety events doing that VOR procedure, also. Flying wide, over the racecourse for example. Yes, it's happened.
The RNAV-X text guidance is published as a 'Technique'. A look at the header in the associated text will confirm. By definition, techniques are not mandatory.
If one is confident the 'pure-VOR' approach from 20-years ago is much superior and will result in no events, the old-fashioned 'VOR or GPS 13L/13R' Lido chart is there for you, and so is the FMS line-selection (all guidance ends 90-degrees to the runway & terminates miles away from the threshold). Just like the old days. Good luck!
