I hate to be a PITA again, but that was not the question.  I'll rephrase 
in order to try to get to the bottom of this:

Why was removing avr/twi.h put on the TODO list in the first place? 
What purpose does removing the file serve?

The file contained absolutely nothing other than a set of #defines that 
provided mostly human-understandable names for all of the various 
(several dozen!) byte return codes that can come out of the TWI 
subsystem (which are identical on every AVR device ever made, afaik). 
Without this file, all TWI code must instead use the raw and utterly 
meaningless numeric values.

There's a reason we dub such things "convenience" macros.
