Free Form I/O with list of fields does not checkl the length of the field vs key of file

I have recently noticed that when using the free format op codes for file i/o, that the compiler does not seem to be testing the length of the fields in my list vs the attributes of the field in the file, but in fixed form, using a klist, it checks the data type and length..

The following code shows the condition:
H option(*srcstmt)                                     
FVArCust   IF   E           K Disk                     
D Comp            S              2  0                  
D Cust            S             12A                    
 /Free                                                 
  Chain (Comp : Cust) VArCust;                         
 /End-Free                                             
C     Cust_Key      Klist                              
C                   KFld                    Comp       
C                   KFld                    Cust       
                                                       
C     Cust_Key      Chain     VArCust                  
C                   Eval      *InLR = *On              
C                   Return                             
 

File VARCUST has 2 key fields:
Company - Packed 2.0
Customer - Character 7A

When I compile this program, I get the following error/diagnostic messages:
          A d d i t i o n a l   D i a g n o s t i c   M e s s a g e s                 
 Msg id  Sv   Statement    Message text                                               
*RNF7066 00        000200  Record-Format ARCUSTR not used for input or output.        
*RNF7073 30        001200  KFLD at sequence number 1000 is 12 long. Key field is 7     
                           long.                                                                                                  


Obviously, this is a mistake in coding, and the cust field should have been defined as 7A, but if the compiler does not catch it, it can take a while to figure out what is wrong when debugging the program.

I have not found anything in the manual that indicates that this is normal behavior for free format i/o.
Has anyone else noticed this condition?
I am at V5R4M5.
I do not know what PTF level the system is at.
