Not exactly what you asked Niels for, but...

A few months ago I recompressed whole buster/main/amd64 to see what the 
effect of ditching --compress-debug-sections would be.
Raw data for this experiment is available here:
https://github.com/jwilk/lets-shrink-dbgsym/releases/download/20200708/buster-main-amd64-20200708.tsv.xz
The columns are:
* file name
* original .deb size
* recompressed .deb size
* original installed size
* recompressed installed size

Note that some of the .deb size savings might be caused by the fix for 
#868674 (for packages that haven't been rebuilt since the fix).
