Taking over the home key will not be done with a permission, period. This is way you get to take over the home key: by having an intent-filter saying you can be home, and letting the user explicitly select your app at the point where they press home. The home key is too central to the user's security for it to be misdirected by some random application they installed a month ago that at time time seemed okay to be able to "intercept home key" (if they looked at it at all).
And as far as the lock screen goes -- nobody has said that there would never be support for third party lock screens. Right now, however, there isn't, and there is no near-term plan to do so. If you want to see why, start perusing the lock screen code starting here: http://android.git.kernel.org/?p=platform/frameworks/policies/base.git;a=blob;f=phone/com/android/internal/policy/impl/PhoneWindowManager.java<http://android.git.kernel.org/?p=platform/frameworks/policies/base.git;a=blob;f=phone/com/android/internal/policy/impl/PhoneWindowManager.java;h=e57fbe8b544b608ba7040b4c1d40b01cd01fe082;hb=HEAD> Lock screen management is extremely complicated, and not in any shape at this point to be user replaceable. At the very least, all of the points of contacts with the rest of the system (complicated interaction with the in-call experience in various states, dealing with emergency dialing that is legally required and the related SIM states that go with it, deep fragile interaction with low-level power management and event dispatching, etc) needs to be deeply abstracted out of the UI itself. And then there are all of the issues of dealing with this now no longer trusted third party code when it crashes or otherwise misbehaves. This isn't just "oh those mean Android people won't let me write a few lines of code to replace the lock screen."
