Yeah, I tend to agree. I know why they made them limited, because they wanted them to be an added feature of the martial classes, but I'd much rather that anyone proficient with a weapon could use its mastery property.
Yeah, but that's the point - because characters only know a limited number of masteries (or none, for some classes), those weapons don't feel different from each other unless you know their respective masteries.1) Because the point was to make weapons with the same damage die and base property feel different.
Battleaxe, Longsword*, Warhammer, and Warpick were all 1d8 versatile (1d10) weapons in 2014. To make them different but still be backwards compatible, they kept that and gave each a different* mastery.
