In the Motorola ecosystem, this is how they save money and make money.
The radios in a tier all come out with an equal physical feature set. By only enabling the features you need, you save money and time having, say, a dozen (or 500) radios all with your unique needs built up at the factory.
Later on, if you need to upgrade or add features, a Motorola dealer can simply take the radio in the back, and most times it's essentially a firmware uplift to add those features, instead of adding physical modules.
It's easy to look at this in a negative light, but, I like it better than having to keep a box of modules and blanks to tinker with radios. Especially when some modules wind up being as rare as hen's teeth.
