What really matters is if the OP wants a USB flash drive that is MBR partitioned, FAT32, and marked as active so it is universal and can be booted in either UEFI or legacy BIOS mode, there is absolutely nothing wrong with that. Or even if the OP doesn't want it to be bootable and just wants it to be MBR partitioned, there is absolutely nothing wrong with that. And if the OP wants to use diskpart to do it with, there is absolutely nothing wrong with that. Maybe we should focus on helping people achieve their desired outcomes.
Maybe a warning that converting a drive from GPT to MBR (or MBR to GPT) using diskpart will erase whatever is on that drive might be appropriate, but I think the OP already knows that in this case.
