Thats disingenous as read() is a method not an interface. It's also wrong
because read() and write() behaviour has changed in various ways and old
code broke because of it in subtle ways. Keeping the same method behaviour
would have required things like new versions of read() for 64bit files,
nonblocking, mandlocks, NFS, networking, etc all of which changed the
core read() behaviour. I've yet to see anyone meaningfully argue it was
the wrong thing to do.
