That's the hope, as classic faction affiliations were dismissed: that the vanilla game (or a future DLC) allows you cop game play of sorts, deep enough so you might not be an actual beat cop or so, but notably more than a hired gun doing dirty work only to have them ignore you afterwards.
A mild sense of "belonging" should be there, just like you would feel after helping a gang or Corp long enough so you become pals, can hang out, enjoy perks, feel a connection.
The goal for this idea is to push something similar for NCPD (while peeking at public interest via vote).
I just think the environment for police related game play is perfect. It's a dark, dystopian, futuristic and gritty world. And such a role fits perfectly. I'm not necessarily talking about a "class" either. I look for seamless game play or certain police content woven into the existing char build or focus. Like doing side quests or side activities or just something you can do seamlessly, e. g. if you have a criminal record scanner. Scan anyone, detain or kill an get rewarded.
Tl;Dr: if there will be some leeway, compromise or sense of belonging (to NCPD or only a particular famous unit of it, you know who), I will be happy.
Of course I'd always prefer the full classic faction experience from a consumer perspective but it was ruled out. So we work from there.
So basically we can only hope for potential leeway in this direction from the devs. The rest they might consider adding via (dedicated) DLC or game addition later down the line, or modders have to bring us salvation. Also depends a bit on the devs, due to that likely requiring good modding support.
No pressure, devs / CDPR
