Product Tags feature is not included in Magento 2

There was a survey conducted at one point on twitter (and maybe other channels) By Elena Leonova asking the community if they use certain modules from Magento 1.
After this survey, the decision was taken to not port the tags and polls modules to Magento 2 because there was not much use of them.
But I'm almost sure someone from the community will implement them for Magento 2.

Yes, Magento dropped this feature from Magento 2. There are no any core module is exist in Magento2.

It indicates that this feature is deprecated at Magento 2

May be #benmarks & @Alankent, will tell us why this feature had removed from Magento 2
