The problem you have with Facom, and I think largely with USAG, is the variety of patterns on offer.Is there a more complete set of the 440XL pattern, or very close to it, sold under another brand in the family? But not the RBRT or any other sets with serrations.
Facom replaced their classic No.40 wrench with the 440, and it’s available in just about every size from 4 to 41mm, possibly some others.
The issue for Facom is that their standard long pattern wrench is the No.40LA, which is available from 19mm.

The short pattern, No.39, is available in the smaller sizes.

And the offset (and slightly longer ) No.41 is also available.

Consequently, they don’t seem to be in a rush to offer a wide variety of the 440XL, which is a shame as it’s a superb design. My suspicion is that the range will get expanded as the design is still relatively new.
The 6 point / toothed 441 is available in a slightly greater range of sizes, but like yourself I prefer the regular wrenches for most uses.
Andres26tnt above, says the larger sizes are only in Mac, which isn’t surprising.
I don’t think there’s anything by USAG, but things are sometimes overlooked on their website.
