Yes,  The current policy is setup to allow most applications to run out 
of the box.  It would
be better to get security context written for the applications to make 
them more secure.

No, but if the kernel does not have SELinux support the apps will run in 
non selinux mode and you
will loose file contexts. So if you later run with an SELinux kernel you 
will need to relabel.

No,  There should not be.
