Description for reviewers

Это на будущее - чтобы потом, при добавлении в настройки индекса дополнительных полей, он отказывался строиться на старых версиях.

Для полнотекстового это не нужно, т.к. там сразу предусмотрели поле Layout.

...Или нужно для всяких доп.полей?... Но если нужно, то тогда отдельным ПР это лучше сделать, чтобы легче было бэкпортить в stable-25-3 многострадальную.
