Indeed, and for reasons I've yet to understand, North America is addicted to the bare minimum cartridge wise, if a .23 is the legal minimum it will be developed and used (no reference to Doug he's in his own category, he shoots up to .577 and is just exploring every avenue). Go abroad and .375 is viewed as a more versatile .30-06, heck my 110lb wife shoots my .375 H&H, no drama, come to North America and its pitched as a beast, excessive in recoil and power. If you want to own just one rifle to hunt the world, the .375 H&H is it. Even if you never leave Canada, that same rule means you are very well prepared all the way up to Wood Bison and Grizzly. And hey, if you can shoot it as well as a 7x57, why not use it if you don't mind the rifle weight, it's certainly not handicapping you in any way. I plan to hunt Roe and Red Deer in Scotland, and the .375 will go for that too as I just know it too well, no point changing gears when the .375 is my most familiar rifle, and if you don't mind the recoil why downsize. If you like it, go for it, being over-gunned is a much easier argument to defend than using the minimum, to extrapolate on Dogleg's point. There really isn't a down side if the shooter is capable of using it and a sturdy bullet is used.
