Yeah. This can not be changed easily. The problem is that ext_update.php 
has no interface and extensions are doing different things in there. The 
access() method is not used as a "needs execution", but extensions 
already do updates if access() is called. So, the extension manager can 
not just execute access() in
the list view of the extension because it would then trigger the update
directly, which is not what we want. I think there are even extensions 
without a class at all in ext_update scripts, so we can also not just 
add an interface for this.
Therefore, the extension manager just shows the update button if the 
script exists and then executes the access() method on click.

This area will probably get some new / additional API with 6.2, because 
we need something for the package handling (introduction, ...) in 6.2.
