It's a friendship thing with the SH pirates. With BB and the rest, it's all about power, but for the SH and their friends, it's about just that- friendship. The Saruyama alliance, for example, is probably the only canon group of pirates that actually consider themselves friends with the Straw Hats, so we can assume that if they ever need any serious help, they would come to aid them, but otherwise, no.
