Agreed.

There are lots of complications with this, for example what happens when
there are transitions, or conflicts between packages that you want
installed.
Implementing this feature in a way that plays nice with the rest of
apt/aptitude dependency resolution would be a very non-trivial effort.

(equivs is also easy to use for this)
There's also the possibility to use user-tags for this purpose, to
remind you why a package was installed by you, in the case that you
forget.
As it is, I don't think that this is going to be implemented any time
soon, and seeing that it was already open for a decade with no action, I
am going to close it as +wontfix.
Cheers.
