But whether you, personally, want any administrative mods to happen

maybe it's justified ... or, anyway, maybe that was the philosophy.
I thought about that as well. On one hand it seems reasonable, but
then I start thinking about what if I want someone else to use the
computer at a later point in time. But then, they're unlikely to be in
the admin group.
One thing to keep in mind: even if you do apply more restrictive
permissions (and I don't mean to stand in your way), the Disk
Utility "fix permissions" step will probably undo your careful
caution.
I believe that Disk Utility will fix permissions only for things the
system installed, possibly looking in Receipts.
At the very least, it won't touch your user folder as I discovered
upon restoring from a backup to find that all of those files were a+x
and Disk Utility didn't do anything about that. I had to write a perl
script using find and file to repair my permissions (and that comment
before about forgetting the leading zero on the permissions, yeah, I
did that for my directory permissions so I ended up with folders
looking like d-w-rwxr-T, oops).
