When symbol versioning was added to rtld, the boolean 'in_plt' argument to find_symdef() was converted to a bitmask of flags. The first flag added was 'SYMLOOK_IN_PLT' which replaced the 'in_plt' bool. This happened to still work by accident as SYMLOOK_IN_PLT had the value of 1 which is the same as 'true', so there should be no functional change.
