Exclude an extension from package uninstalling

[Soheil Novinfard]

hi friends,

Is it possible to exclude an extension from package uninstalling? I search script.php for any related methods, but It seems not possible.

PLEASE help me, 

Thanks,

Maybe alter the package manifest (remove <file /> xml element) from
within package script file?
Seems that there is no preflight for uninstallation, but you may use
installer constructor:

public function __construct(&$parent)
{
$manifest = $parent->get('manifest');
// Select extension xml elemnent
// remove from manifest
}

This is just idea, didn't try out
