need fixing) as soon as a page is "moved" (t.i. renamed).
My question is: which is the sound reason for this strange thing? There's
some idea about fixing this?

That's how it used to be before 1.5
There was a links table [1] and a brokenlinks table [2].
Then if a page was created/deleted/renamed all entries referring to it
(which could be large) would need to be migrated/updated.
Using the pagelinks table avoids all these problems (at the cost of some
more space needed for existing links).
Also see [3] and [4].
