work. And it removes the need to do 1., 2., 3.
This thread, and my own tests, showed that you need to assign GUIDs to
interfaces to have reliable "is", even for CORBA interfaces.
I'm wondering, would it be possible to improve here things on the
compiler side (at least only in FPC-specific modes or under some
modeswitch), to make things safer?

MSEide is awesome. I use it for Console, fpGUI and even LCL programming.

But you must still remember to check if abcintf has been successfully
assigned.
[personal opinion]
Hence I still prefer the Supports(..) call as it can be used directly in
a boolean expressio

No definitely not! The GUID just helps the compiler or RTL identify an
Interface.
Oh fabulous! Thanks much. I def

I'm not sure. I just had a look at my code. It seems all my [Corba]
Interface have GUID's defined too. I never noticed - probably down to

I've been using CORBA style interfaces for years, and it was always
worked well for me. I must add, I never use the is/
