If you mean creating the VMT at runtime, then the
answer is: yes, it 
still
does.
What are the alternatives?

Mattias

Yep I meant creating VMT at runtime,It does not seems
like a good practice to me. 

Delphi's streaming system wont work without RTTI, and 
Delphi's RTTI is only for streaming. RTTI and message/
dynamic methods is embedded in compiler to support VCL
and IDE. So writing a Delphi-like IDE without support
of FPC team / compiler could be hard work but I still
wont think 
creating VMT in runtime is way to go. Cross-platform
issues and these kind of hacks/ shortcuts  is
overcomplicating things in Lazarus codebase, I think.

Alternative? 
I prefer a solution based on non ref-counted
interfaces  for example (although this may need some
support from compiler side e.g UID's for non
ref-counted interfaces/ interface delegation or
something, and means nearly rewrite, so I dont think
this will happen)
User-level delphi compatibility is enough for masses
(e.g Form designer, properties vs), as long as it have
quality/stability,  internal workings of components is
not so important, but as I said above, with current
implementation I dont think Lazarus is
production-ready or it will become.

Sorry for my poor English.
