I think one BB10 model goes with 2 LTE versions and 1 CDMA verion is enough but Blackberry released 5 versions for each Q10 and Z10 for what?
Yes, it may reduce cost with STL100-1 and STL100-3 RFF91LW but ...
This makes customers who can only buy one of those two versions in their country will wonder why their phone got different quality and different hardware (chipset). Some Apps/games are not running smooth on STL100-1 but are running smooth on other versions. Customers may feel that they are discriminated.
It's hard for users to discuss on forums about hardware, software, OS issues because of same model but different versions, each version has its own OS.
It also costs developers a lot of time and effort to make the apps, OSs compatible with each device version ----> late OS release -----> cannot satisfy all customers.

Just as there are different car manufacturers.... there are different cellphone carriers that use different hardware and different frequencies.
Some of this is mandated by government (frequency availability) and some by evolution of carrier hardware upgrades.
If you think Blackberry is bad.... Android is far worse where apps will work on one device and fail to work on another.
