To answer the first question, for me and for many I think privacy outweighs the desire to have a personalized
address, one of the most important features of Bitcoin is privacy and this method can pose a threat to privacy.

It is true that the idea of obtaining a personal address that expresses personality instead of these long numbers and letters is an attractive idea, but unfortunately it reduces privacy, so I do not think that many people, especially in countries that have problems with bitcoin, will like this idea.
