No one wanted to spend the time on all the third-party packages that still use that API. What's worse, back then even the CMF packages were not switched to a pure utility model and would emit these warnings as well.

AFAICS the only thing we need to do for backwards compatibility is using 
registerToolInterface. So it isn't urgent to deprecate and remove 
getToolByName.

It might be useful to write a howto for people who want to modernize 
their code.
