I know how smartlinking works ;-)

But that doesn't mean it couldn't be minimized. The question is more if
anybody cares enough to do so, IOW where is the real problem?

No. Dynamic linking/packages doesn't really solve anything. It only
fragments the units over multiple binaries.

Anything like that can also be done on the unit level (with minimal
abstract base classes and the real thing only kicking in if you use
certain units that register the derived classes with all the code
and depedencies).

See e.g. how Free Pascal handles similar problems on RTL level to
keep thread and localisation support out of the binary on *nix.
(cthreads/clocale). Though that is more because of dependencies/deployment
than binary sizes.

Sounds like a canon to shoot a mosquito.

"bloat" is so horribly subjective. As said, most people see no problem
in wasting ten times the space due to browser caches.

So why should Embarcadero spend a significant percentage of their
development budget on this? Better they start fixing bugs with it :)
