Otherwise, we can get in a situation where the single item is flexible,
and we replace its attributes with the attribute of the lower bound,
which messes up `EnhancedTypeForWarningAttribute`.
#KT-65193 Fixed
This commit in fact changes two very related places:
- first, it implements forgotten 'enhancedForWarnings' in K2 enhancement
- second, it repeats KT-48515 fix for K2 while enhancing wildcards
#KT-65594 Fixed
Related to KT-48515, KT-63746
This commit changes the behavior of KT-59138 effectively declining it in 2.0.
However, we plan to implement KT-59138 behavior under a feature
flag in 2.0 (see KT-66447), and switch this feature on version 2.x.
Also, this commit implements the LC resolution about postponing
KT-57014 change. We don't have KT-57014 described behavior in 2.0 anymore.
However, we plan to implement a deprecation warning here, see KT-65578.
After this commit, 6 diagnostic tests become incorrectly broken:
- 5 tests from PurelyImplementedCollection group
- a test platformTypes/nullableTypeArgument.kt
This commit also breaks currently fixed-in-k2 KT-50134
(it is fixed again in the following commits),
as well as KT-58933 (it will remain not fixed till we enable KT-59138
behavior again).
