So most of the growth in Han characters is caused by people inventing and registering new sinograms for their own names, using the basic principles of combining a phonogram and a distinctive semantic character.
This is not correct. It is certainly not correct for CJK characrters added to Unicode, and to the best of my knowledge it one just makes up a new character for one's name it is now no longer possible to legally register it anywhere that uses Chinese characters. Take Extension F, over seven thousand characters of which nearly three thousand Japanese characters in Budhist texts, over one thousand Zhuang characters, naerly two thousand characters used in Korean historical texts.
