Really? The 'needrestart' package seems to do quite a good job of this. 
The main issue is that, if a library is upgraded, then a long-running 
process probably won't notice (aside: on Linux, one can delete a file 
and replace it, but a process with a handle to the old file generally 
won't be affected). needrestart scans the process table after an upgrade 
and, if a process has a handle to a deleted library, it is noted. If 
that process is part of a service, needrestart gives the option to 
restart the service. If the process is part of user session, then 
needrestart can pop-up a message telling the user to either restart the 
application (e.g. in the case of their browser) or to logout-login (e.g. 
in the case of a window manager).

Now, it may be the case that there are so many applications running that 
it's just as easy to reboot as it is to close and restart them all, but 
that's up to the user.
