And there wasn't an extended "Bat-Family" that had a dozen members?
I remember the late 80's early 90's when Bats was a solo act and IT. RULED.
Then you had Tim Drake as Robin which, fine.
Then Jean Whats his face who was raised by the evil monks or whatever.
Spoiler.
That silent Batgirl.
Suddenly Dick Grayson is mere minutes away in an even more corrupt city than Gotham.
Now you have Bats, Dick, Jason, Tim, Babs, Catwoman, that black kid, Damian, Ace and of course, Bat Cow.*
If DC is gonna have a zillion books about Bats and his 'family' they damn well better have one devoted solely to the adventures of Ace The Bat Hound.
*Yes, yes I'm sure I left some people out, you get the idea.
