I fully agree with this (going ahead with the work), it's just a 
question of whether we want to fill people's error logs with warnings or 
not. Perhaps we could start off at a lower error level for a version or two?

Changing every use of getToolByName() in every product out there 
(especially Plone's third party products, of which there are hundreds) 
is an enormous (and fairly daunting) task. If every request gets four or 
five of those messages, it will be counter-productive, swamping the logs.

Similarly, if we did remove it too soon, the breakage would be enormous. 
Probably so much so that Plone would need to monkey patch it back.

I completely agree that the "new way" is better. I just think we need to 
be pragmatic about how strongly we warn that there is a new way, and how 
quickly we remove the old way.
