FileReader is still ED, therefore we may have time, I think.

Agreed.
I have been thinking in terms of API design patterns and IMHO their target is to first document what we have in order to be able to foresee potential incompatibilities.
That is why I shout early :)

Thanks,

To be clear, IMHO it's absolutely too late for FileReader, and also not
desirable.  I've already mentioned developer familiarity with onload,
etc. and I strongly disagree with changing names in this case.  The
existing progress events are fine for FileReader.  We've also got a beta
implementation in place in Fx 3.6.

Regarding FileWriter, I'm open to considering new event names, but in
general, discussing FileWriter's event model may be putting the cart in
front of the horse.  Even if we had an event-driven FileWriter, what
would it do?  We'll need to figure out filesystem access (real or
virtual) first! :-)  More on this topic in separate email.
