Thanks for clarification!

So far I couldn't reproduce my "problem" anymore and I think I just made
a wrong observation.
Initially I asked because I was pretty sure I had a binary package of
traceroute-2.0.18 which I believe were deleted after I upgraded to
traceroute-2.0.21.
However, I did some tests and it seems traceroute was the only example I
could find were this happen and now I'm not even sure if I ever had an
binary package of traceroute-2.0.18.

Here is also a brief explanation of what I'm actually trying to achieve:
A few weeks ago I set up another gentoo system on a rather old system
(core2duo/4gb ram/1TB storage). Since this one should be just a computer
for toying and trying around I thought about to put rootfs on a lvm 
partition so that I can easily clone the whole system.
This works flawless. With a little nice script I've wrote myself I can
easily clone/delete/backup/restore complete system's in minutes, which is
why I already have 6 different systems.
	- gentoo_base
	- gentoo_cinnamon
	- gentoo_gnome (with systemd)
	- gentoo_kde
	- gentoo_kde_testing
	- gentoo_lxqt
I guess the names are self-explaining. 

Moreover, I also had the idea to share similar packages across these
systems. This would mean, if I already installed xorg on
gentoo_cinnamon, I don't have to build it again on gentoo_kde. In this
case binary packages are a big win. Only packages with different use
flags would be rebuild. It's especially handy on packages like firefox,
chromium or libreoffice. :)

After I though old binaries were deleted I was eagerly to find a
solution for that, since it would make my setup less practical.
After all I should have checked other packages more carefully before 
asking stupid questions, but laziness lead me to my initial mail...

Anyway:
Older packages are kept, so everything seems to work as expected. I've
also checked for rm/elcean in cron and other places were it could run
automatically but I couldn't find anything.
I also tested on different systems with different packages. No problems
so far.

I'll keep an eye on it, but I guess there wasn't really a problem.
