The big takeaway from this war is that loitering munitions such as:

have "come of age".
Basically, all of the loitering munitions have a 20-30 kg HE-FRAG warhead and can either operate in:
"Fire at predicted enemy concentration, autonomously search for targets, if no target found either self destruct or return to base"
"Man in loop control" with someone watching the video and confirming what to strike or not.
And because they're smaller and move slower than "traditional" air defense targets, they're overlooked by conventional SHORAD/Air Defenses.
Then again, like in Operation Desert Storm, we're only seeing the "good" videos of successful loitering munition attacks; the Azerbaijani MoD isn't going to post video of them being shot down or missing their targets.
