So if I have

package P is
...
   package Q is
      ....
   end Q;
end P;

then with most compiler, Q will not be linked unless it is referenced

That's a good news

In the mean time, I know that a lot of Ada users don't bother about
plus or minus 150KB, so it's not a surprise if some compilers don't
bother about it.

Adam, are you a member of a compiler vendor team ?
