[Serhiy Storchaka]

Serhiy Storchaka added the comment:

Sorry. I were understand that patches were approved by several core devs. This issue was created for fixing regression from issue16045, but then I saw yet some forgotten deprecated asserts. If you want, I will revert this additional changes in 2.7 and 3.3.
