f.pos += delta

That's the only part of the proposal that I really think is an improvement
over the current method:

f.seek(delta, 1)

I actually had to google the whence code for relative seeking which I
wouldn't need to do if it were more descriptive.

But then I never do relative seeking. I'm pretty sure my programs have
always either read the whole file in order with no seeking or used random
access with absolute seeking.
