package.el, package updates and load-path in long-running emacs

[raman]

User Scenario 

1. You dont restart/kill emacs very often.
2. You use package.el and  update packages.
3. This deletes older versions of the updated package.

Now, load-path is full of dirs that dont exist --- worse -- unless you
run package-initialize, the newly updated packages are not found by
commands  like  find-function.

Suggestion:

At the end of updating packages, we should perhaps run 
(progn
(package-initialize)
(setq load-path (remove-if-not #'file-exists-p load-path))

Sounds reasonable, but what is the full impact of running package-initialize
at that time?
