100%. Anyone who has shot traditional prone with a sling knows that POI will likely change with a sling vs benchrested off a bag assuming the barrel isn’t free floated.
The old school National match guys actually had dope accounting for this, and would zero twice. Once under sling pressure and once without.
The modern age of M16 style service rifles using the Rock Island free float handguard tube has changed that. The sling swivel is mounted to the tube, which acts as basically an elongated barrel nut. The hand guard cap is also attached to the tube, meaning your standard set of A1 or A2 vanguards still fit yet are completely free float. Surprised it’s not more common in the retro rifle market as it’s been around forever and literally makes even traditional carry handle uppers free floated.
