My two penn’orth… I’m biased, coz I own one (LOL), but the Classic is a great drone.
The Classic is officially “obsolete”. I can’t find it listed on DJI’s store anymore and the software (active track and RTH) isn’t as slick as on DJI’s newer drones. That said, it still flies very well, acts like it’s nailed to the spot in high winds, and will be A1 (Fly Over) from January 1st.
It only has the one (wide) camera, but it’s an awesome 4/3rds Hasselblad system that gives fantastic photos and 5.1k videos @50fps. I don’t miss not having a Tele lens, but I think I would miss the 4/3 sensor. I don’t think you can get better photos or videos (except on the C2 Mavic 4 series)… and as a wise person once said, size does matter. 
It’s an awesome drone which I would buy again in a heartbeat… though I hope that day doesn’t come soon, coz it’s still selling around the £1500 mark IIRC and I’d wince at spending such a lot, or justifying the spend to my wife!
It’s not going to fall out of the sky, or suddenly give rubbish images or videos, just because DJI have moved on to shinier things.
I will buy a Mini 5 pro “soon” - mostly to acquire the slicker software and the ability to operate in “stealth” mode near people (the Classic is big ‘n’ fat and draws attention) - but I’m sure the Classic will remain my go-to drone for the foreseeable future.
