My decision was taken after reading a message posted here by Chris Nebel.
Alas, at this time I don't retrieve it but retrieved a message from Paul Berkowitz reporting it :

No, Chris specifically announced in person on the AppleScript Users list at
the time that Jaguar was released that he had changed his mind and his
advice. First of all, System Events will be sticking around for the
foreseeable future. Secondly, they've now started adding new commands to
System Events, which will never be added to the Finder: "Legacy" items and
commands in the Finder are just legacy. Thirdly, it's faster sending the
commands to System Events. So you've got the all-clear to use it.
There's no point asking Chris by name. He announced here last week that he
was getting back to programming and wouldn't be corresponding to the list.
he did say that other members of AppleScript team would participate here:
sure enough, one day later, three of them appeared. No one has appeared
since then, except cricket for Mail, and he had been doing so all along. I
fear that our great days of active involvement by Apple engineers is over
for the time being. (John Delacour evidently must think so - another day
later he made what seems to have been his last appearance since his
resurrection, after having let us know that he only participates on this
list because of Chris. Either that, or he got too annoyed by my Unicode
obtuseness. Or maybe he's just busy. ;-))

On my side I have no offset problem with System Events because my scripts are triggering it so often that it's quite always available in ram, exactly like ASObjC Runner.
