'Apply_to' column from catalog_eav_attribute has strange behaviour

[firestorm23]

Environment

Magento 2.0.2, local server, Windows 10

Steps to reproduce

A.

1. Create an attribute 'testA' with Dropdown type through InstallData.php and fill the column 'apply_to' from table 'catalog_eav_attribute' with some product types, e.g. 'simple'
2. Try to add a product with Configurations, choosing 'testA' attr. as config. option.
3. This 'test' attr. will not be seen in the Configurable options

B.

1. Try to add attribute 'testB' through Admin, from Congigurable attributes modal, after 'New Product' -> 'Configurations' steps
2. Created attribute will have column 'apply_to' set to NULL

C.

1. Set the column 'apply_to' for 'testA' to NULL
2. Try to add a product with Configurations, choosing 'test' attr. as config. option.
3. This 'test' attr. will appear in the Configurable options

Questions:

Does the 'apply_to' option is still legit for Magento 2 ? Does it change some behaviour ? I cannot find it on the Admin.

As I see, this column effectively changes posibility to use current attribute as option to create configurable products. Is it a part of stable logic or not ?
