This will probably NEVER happen but you never know.
The only reason why Sony doesn't want us to use homebrew is because emulators and ISO loaders are illegal. I know sony can't make a firmware that will launch homebrew and not ISO loaders, but what if we could convince sony to sign our eboots as long as they aren't emulators or ISO loader. Then we could have our homebrew and Sony will be happy with no emulators or ISO loader.
If only it could happen.
