It does not screw up things with session variables. The difference between 
session variables and application variables (I would say) is the scope. (Both 
are persistent between several requests.) There are ways to assure that 
requests are served by the same machine if sessions are used (load 
balancers). There is also the way to set up a central storage like you 
already can do with session_set_save_handler().

We two obviously have a different  concept of application variable. As I 
understand it, you would never share applications variables between different 
domains (without the php programmer knowing that). But you are right, if you 
i.e. run a web application on a shared host, you could have a single 
directory served by several different subdomains, e.g. webapp.mydomain1.com, 
webapp.mydomain2.com, webapp.mydomain3.com with all domains mapped to the 
directory htdocs/webapp. But the programmer of the applicaton would have to 
consider this, not php.

But as I said earlier, I was more interested in knowing the rationale why this 
feature hasn't been integrated yet, than in demanding it.:) (Right now I have 
no patch, either.)
