Well just imagine this situation:
In your top level TS you load  ExtCore
(page.includeLibraries.ExtCore=1). In some sub-page extension template
you include an extension template that loads ExtJS
(page.includeLibraries.ExtJS=1) .
You will have difficluties to find the problem.

The check will of course only be effective if you use the TypoScript
shortcuts:
page.includeLibraries.ExtCore
and
page.includeLibraries.ExtJS

It will not generally check for conflicting libs.
