I never run this command. I have AppleScripts that I have developed to arrange icons in a specific place, rename them, and so on.
I also never use Auto-Open posting. It's an old technique that is superseded by what sequences can do.
When I wrote the first version of the CRM mobile app we were in Swift 2. Then came 2.2, 4, 5, and so on. Each time, the app required a rewrite, both because new and better things were available, but also because some stopped working, or never really did (Auto-Layout).
I respect your desire to maintain old systems. However, I wouldn't suggest it to anyone. I can't tell my clients that their program only works on an OS that is 10 years old, or more. The expect me to keep up. It reflects badly on your company's ability to adapt to changing programming conditions.
There are a lot of folks that are committed to one feature or another in Helix. The figured out a way to use it that they like. Some of these will undoubtedly disappear in an upcoming release. We simply don't have the same OS we had in 1983, and Pascal, as good as it was then, is not a reasonable language to work in today. Things change. As developers, we have to be creative and come up with news ways to solve each of the issues in question. The only way thru time is forward.
