Has there been any consideration by TWRA to legalized the use of primitive weapons, such as the single-shot 45-70 during primitive weapons/muzzleloader season?

I know the 45-70 is consider a primitive weapon and can be used during muzzleloader season in Mississippi. With the advancements in today's in-line muzzleloaders(accurate to over 200 yds), as well as, the fact that the 45-70 single shot is a primitive weapon, I personally don't see why we can't now use other primitive weapons, such as the 45-70 during muzzleloader season.

Any input from TWRA would be appreciated. Thanks
