While I personally agree with you, I also think for the majority of users a "condensed" changelog is more suitable.
For example, the entry "Corrected cockpit and external 3D models." includes ...
- ~20 individual errors (for example typos/wrong positions) fixed in the exterior model
- Texture DIF File: There was only one set of gun port textures
- Wrong Pitot Tube Model
- Variable Sight Selector Unit "MILS" label missing
- Airspeed Indicator missing caret
- Fuel Quantity Gauge Texture Error ("X" missing)
- Radio Compass Indicator: Label "VAR E W" missing on the knob
- AN/APX-6 IFF Panel Left screw missing
- AN/APX-6 IFF Panel Bottom left: screw wrong color (black -> red)
- AN/APX-6 IFF Panel Right: Destruct label missing on switch cover
- AN/ARN-6 Radio Compass - Tuning knob is actually a crank
- AN/ARN-6 Radio Compass - Light switch "HI" and "LO" labels missing
- AN/ARN-6 Radio Compass - Function switch: "CONT." position missing
- AN/ARN-6 Radio Compass - Screw/light missing between AUTO and COMP labels
- AN/ARN-6 Radio Compass - Index marks missing on top of Function switch and Loop L-R switch
- AN/ARN-6 Radio Compass - Round "hole" for tuning meter display missing
- AN/ARN-6 Radio Compass - LOOP L-R arrow is actually two individual arrows
... and several more fixes - the list is not complete.
If all those fixes / tiny details would be listed individually, assembling the changelog would take a lot of care and time. Also the changelog would be of immense size and would confuse some people.
On the other hand, it would show the love ED and 3rd-party-developers are putting into their products.
