For Debian and Debian derivative stable systems, "autoremove" is the recommended apt command to remove packages that are obsolete or orphaned, and no longer needed by the system. But "autoremove" has never, to my recollection, been recommended for use on sid, due to the rolling nature of package introductions and transitions.
Since sid is at this moment pretty stable due to the upcoming Stretch freeze, I thought it might be worth an experiment to see if I could clean up a couple of my systems without damage. Both of these systems are a couple of years old and came through the plasma 5 transition last year, so I guessed there was quite a bit of cruft laying around in them.

As far as I can see after a couple hours of my normal operations, nothing on the desktop or in the system was adversely affected by this huge dump of cruft. I usually keep more than two kernels but it's no problem this time. There was a message that two of the old linux headers directories were not empty so they were not removed -- I will hunt them down manually.
Before I did this to my desktop rig, I did the same thing on my laptop which is an HP/Intel platform, and there were no issues on that one either.
So, bearing in mind this is not recommended by anyone, I found it a useful experiment.
