We had an IO abstraction layer a long time ago. The original one was bulky, hard to debug, and didn't solve the problem it was designed to solve, namely filtering. When the filters were introduced, the IOLs were removed, because they were no longer needed.
I guess my only question, is what problem are you trying to solve with an IOL? Until we have an answer to that, there is really no way to know if they are a good idea or not. Every time that they have come up in the past, the reason was never enough to justify adding the complexity and performance problems. Remember that in general, an IOL would mean that every time you wanted to read to or write from a file or network, you would do a pointer de-ref and call an extra function.
