Yes, the whole reason for targetSdkVersion is to allow the platform to turn
off various compatibility behavior for older applications.  If you bump up
your SDK version, you are saying you have fully tested your app against
that SDK version so are not relying on any of the older compatibility
behavior.

You can see many many things listed here that are impacted by SDK version:

Actually there are a number more that aren't spelled out so well in the
current public doc (but are usually documented at the APIs that are
impacted).  I also recently in our development tree went through and tried
to get in the documentation in VERSION_CODES everything that is impacted by
targetSdkVersion.
