EXEs are only memory mapped, and not the whole binary must be in memory. 
Unused parts are unloaded in low memory circumstances.  (though with 4k
granularity for 32-bit and 8k for 64-bit).

Moreover, for most non trivial applications, datasize allocated by an EXE
dwarfs the code size.  If you persist in that way of thinking, I think the
growing of TObject in post D2007 versions might be a much worse thing that
dwarfs binary size issues.

Yes. And I fail to see how a 300kb difference will make a difference
in a world where entry level machines are equiped with at least 4GB memory.

The result remains the same. It is the refactoring into a minimal interface 
and the full implementation that causes the savings. Not the dyn
usage itself.

If such refactoring was done, Embarcadero could have simply only link
the bulk of the code in when needed.

That is not true. Packages can also be dynloaded, specially if they 
override base types that are statically linked.

Packages are the same as dyn linking in most ways, just under control
of the compiler.

If you only put the themes unit in the package. BUt if the RTL contains
an abstract themes, you could load the full version of themes dynamically,
theoretically.

That's the exact point I tried to make in the dynamic library package.
The organization for minimalistic purposes isn't there. And then
it doesn't matter if it is statically or dynamically linked.

But afaik Delphi allows recompilation of the RTL/VCL? Simply cut out
themes, turn extended RTTI off?

Lazarus uses fpc yes, always has, the projects have been linked since
Lazarus' inception. (FPC is older)

But Lazarus has binary size overhead due to its multiplatformness, and 
is slowly increasing too.
