Although the message from Apple is reassuring, I wanted to check what would happen if I replaced ARDAgent.app v3.2.1 (installed by Software Update immediately upon upgrading from Tiger-erase-and-install,) with the previous version 3.2 that came with the Leopard DVD install.
Before that, I tried to repair permissions in Terminal '$ sudo diskutil repairPermissions /', when the new version was present and active, and got the same results as reported by other forum members who used Disk Utility, the warning etc...
After replacing v3.2.1 with 3.2 and restarted, the same command in Terminal gave a clean output.
I launched Software Install, and it brought the 3.2.1 update, which I didn't run, and I have still v3.2.
I believe this means that Apple has not discarded this update from its Software Update servers, and there must be a good reason for that, not negligence or overview.
The blurb that came with the 3.2.1 update reads: "Apple Remote Desktop 3.2 Client Update
The 3.2 client update is recommended for all users and addresses numerous issues related to overall reliability, usability and compatibility.
NOTE: It is recommended that Apple Remote Desktop version 3.2 Clients can only be managed by Apple Remote Desktop version 3.2 Administration software. Please ensure that you have upgraded your Apple Remote Desktop Administration software to version 3.2 before upgrading your clients.

I am not using Apple Remote Desktop, and I am not experiencing any of the possible problems detailed in the above link. On the contrary, everything seems to run extremely well.
I am not going to recommend to restore v3.2 or to install 3.2.1. I have this Macbook Intel Core 2 Duo running with ARDAagent.app 3.2, and a Powerbook PPC running version 3.2.1 (where Disk Utility's output when repairing permissions has indicated all the warnings that have already been reported by other forum members.
I hope this will enable me to compare, although we are talking about totally different CPUs.
I do hope Apple kicks in any time soon with a practical solution that would be better than its previous reassuring message.
