I suspect that the code must have been a work-around for something that had been fixed in MDEV-12610.
In MariaDB 10.2, fil_node_open_file() computes the local variable first_time_open and will read the encryption metadata when reading the first page for other reasons. In 10.1, the code looks a bit different, but I think that the logic should be compatible.
