It's not like she lost her peerage or anything. High-class pureblood devils that already have evil pieces have no reason to become someone else's servant. Those high-class pureblood devils that are servants give up the right to have evil pieces and get their own servants. Grayfia, Ravel Phenex, Kuisha Abbadon(Sairaorg's queen), Serataas Barbatos(Magdaran Bael's queen), Beruka Furcas(Sairaorg's knight), and Gandoma Balam(Sairaorg's rook) are a few examples and I'm sure there are plenty more. Not every devil wants to get evil pieces and look for servants and become a king. Some high-class pureblood devils would rather serve under another high-class devil and become that devil's servant and get the benefit of an evil piece and not worry about having to command. And the reason why Sairaorg has 3 pureblood high-class devils in his peerage is because he belongs to the House of Bael. The Baels are the highest ranking family in the 72 Pillars so it is kind of traditional for devils of lower houses or those of the Extra Demons to serve under them. That has a lot to do with it.

Her becoming Issei's servant would be a waste of a piece. It just said she couldn't compete as a king for a while and lost her status as an Ultimate-class devil and as the 2nd ranker. It's not like they took away her servants.
