When a character doesn't get much attention in that way, it generally means one of two things: either they just don't interest me (and therefore don't spark much in the way of story ideas) or else I haven't got around to them.
In Shiva's case it is mostly the former. However she is due to be discussed in the not too distant future (and by a weird coincidence she's due for an appearance in the Gotham Post too!). If in the course of either episode she strikes a spark, you never know, we could wind up seeing her in person.
“Do you, Bruce Wayne and Selina Kyle promise to forsake all others and reserve your warped, angst-ridden, dysfunctional nincompoopery for each other, thereby saving at least two innocent people and providing untold hours of fascinated diversion to the rest of us who might otherwise think WE have screwed up relationships!”
--Dick Grayson in a moment of clarity
