Yes in theory of SEO it would help, unfortunately osclass is not designed for that.
Honestly I was playing with this for several days some time ago, but it is quite complicated task to redesign this. Currently it works just for static pages, you can check i.e. on Gamma demo.

Another problem I remember was, that i.e. listing page can use any slug, also translated, in url.
And there is much more of them. Maybe there will be time in future for that or simply someone will have enough will to play with that and provide what should be updated
