Could we get some rationale behind changes?

No, that’s a fantasy. No one obfuscates the code like this. I mean you say later on, that this is an unlikely scenario. But that’s not just unlikely, that’s unreal.

Sadly, such things are destined to fall apart. I already wrote about it, so I am not gonna repeat myself

I would love to find some hole in that logic, but I see no outs. There is 4 options:

  1. The devs are doing nothing.
  2. They work on a secret project.
  3. The code is awful.
  4. Business process and communication inside FS are awful.

And all 4 options are bad. Not equally bad, but bad. And moreover, several of them might be true simultaneously.
