So my interpretation is that the only NEW thing made possible by such statements is that it is possible now for some people to establish Swahili medium secondary schools, and it is now official that local government authorities can convert existing primary schools to become English medium. 
Kwa hiyo tafsiri yangu ni kwamba jambo pekee jipya linalowezekana kupitia kauli kama hizi ni kuwepo kwa uwezekano kwamba sasa baadhi ya watu wanaweza kuanzisha Shule za Sekondari zinazofundisha kwa Kiswahili, na kwamba sasa ni rasmi mamlaka za serikali za mitaa zinaweza kugeuza shule za msingi zilizopo kuwa za Kiingereza.
