Hmm - reason for installing package...

Question

All,
I'm not sure if this issue has been brought up before, but I want to get some feedback about a pacman idea that I had.
pacman -Qi lets you see dependencies for installed packages.  It helps you see why you installed a package.  Super helpful.  But it doesn't show everything.
Sometimes you've installed a package because there was an install-time recommendation for another package.  Or perhaps I was writing a python program and tried out a library, but then later used a different library and so the library is still installed, but not being used.  In cases like these, there may be no clean way to hook up an installed package with the "reason" it was installed.
My idea is to have some type of flag on pacman where I can record the reason I'm installing a package (or group of package).  Then that reason will be stored for when I run pacman -Qi later on.  It can just be a one-line piece of text.  No need for anything fancy.
pacman -S python-sqlobject --reason "trying this for project blah"
It might also be helpful to have a flag where you can set the "reason" on a package after it's already been installed.
pacman -Q python-sqlobject --reason "trying this for project blah"
Then, later:
> pacman -Qi python-sqlobject

I envision this being extremely helpful when cleaning up and administering packages on my system (for me personally).
Can anyone see the benefit of this?  Has this already been brought up?  Are there simpler solutions people are already using? ...

Answer 1

I actually think this is a pretty good idea, but I'm not sure how many would use it.  I often run across packages on my system and don't remember installing them even though pacman says I did it explicitly
