Perhaps they will have current improvements as the SA to utilize the latest JHP ammo and perhaps mag disconnect.
Browning left a void when they stopped production.
At the request of Browning, FN re-designed the Hi Power feed-ramp to the "flat style" around 1980. Most any post-1980 FN Hi Power's you'll find are not too picky about ammo at all. In fact, they tend to be dead nutz reliable.
Metallurgically however, newly manufactured Hi Power's have some steels, and manufacturing processes available to them today that were not available in 1935. So while I tell people to steer away from NATO pressure, or +P in an FN Hi Power (or copies from the same era), I tell people to blast away all you want with these new ones.
So yeah, they thought of that and addressed it.
On the subject of the magazine safety, the Turks opted in on the magazine safety. Keep in mind, there are still a LOT of military customers out there who would like to be able to buy parts for their old Hi Powers, so they stuck to a design that is parts interchangeable with the later style Hi Powers. Springfield chooses not to include a magazine safety in theirs, but they seem to be the only ones doing that at present.
I suspect the Turks are even getting orders for new Hi Powers from military customer in the Middle East and Africa, where the Hi Power has a bit of a cult following.
