During the time of TNG I don't see most of the crew, outside of Beverly Crusher, calling Picard anything other than Captain. Now once he's retired that's a different story. I can see Riker and Troi calling him Jean-Luc. Perhaps not Geordi. I'm thinking back to "All Good Things..." when he still referred to him as Captain, or Admiral. Worf probably would still refer to him by rank out of habit and probably respect.
JL, that's strikes me more as a unique nickname that a single character might create. Many have those friends that they're the only person that calls us by a certain nickname that doesn't catch on for others. Or in some cases maybe we only allow one friend to call us by a particular name. I have one friend that insists on calling me "Chuck" based on my middle name, which is Charles. I think she does it partly because she knows I'm not fond of it. But I kind of let it go. But I don't let other people call me that.
I'm just not sure why this is a big deal for some. I can't see Riker ever calling Picard JL. But not sure why that would preclude another character calling him that. Maybe Picard doesn't like being called that, but in that characters case he's just let it go or has gotten used to it. I'm not sure what the big deal is.
