OS X already hides the ~/Library folder, it's not far-fetched to think they might hide everything but the Photos, Documents, etc. folders.
I wouldn't say iOS is a terrible product, just that it's terrible for someone that knows how to use a computer. Apple is trying to get users that don't know what they are doing at the expense of the experience for users that do. I know I shall never buy another Apple computer if the trend continues.
You'd have a better argument if they got rid of the Library folder completely. Just because it's not a single click away anymore doesn't justify the slippery slope argument. OS X is not Linux. It's targeted to the general computer using populace and happens to be quite popular and useful for a very small minority of people like us. They still allow us to do everything we used to, it's just that they've hidden a few things that confused the normals out there. Big whoop.
Hold down Alt while clicking the Go menu to see your Library folder.
Your assertion that it isn't a slippery slope is subjective, as is my assertion that it is. Both viewpoints are valid.
However, I reject your solution. It's my machine, I want it to be a pleasant experience to develop on, I don't want to memorize a workarounds for a bunch of trivial problems that I have to apply to every machine I use.
I'm taking the defensive position of not investing too much of my time in their products because I think they will remove access to those folders, or lock down on application installs, or otherwise make the experience wretched for me sometime in the future.
