Yes, I understand that.

**_BUT_** it has **_NOT_** been promoted by **_Maven_**. In the bug report and in this PR I do not see any explicit recognition of how this change will impact the community that is using Maven and I am suggesting that this is a significant proportion of the community.

For example, all the libraries that use annotation processing that document maven use could be impacted along the lines that their documentation will now be at least misleading (and sometimes incorrect). 

This change might indeed be a good long term change but it seems to be being made without any recognition or understanding of how impactful it will be.
