Indeed.

Disagreed. Those are implementation details, may vary from target to
target, may depend on the assembler/linker rather than on FPC, etc. What
I wrote is just the high level idea. When you have e.g. published
properties and their RTTI, you can easily start having a lot of hidden
references.
