Remaster doesn't make sense if the game was rebuilt, regardless of how close to the GC versions you think they are. The recent Crash games aren't remasters, those games were rebuilt.
Remastered games are essentially cash grabs because yes, they're ports with graphics more suited to the target platform. Remakes have more time put into them. But yes I do agree with you about RE series having pov switch, sorta like TES/Fallout games have had for years.
Survival/horror games and first person in particular go very well together. Look at Alien Isolation.

I've commented about RE needing first person for years, RE4 is a legendary favourite for many people but Leon's body is just filling the screen.
RE7 was good for fp but I didn't enjoy much else about the game tbh.
