Michael, I have two options to solve this:

1) Ignore Marco and implement it any way. I think you have just as
much say as Macro on what goes into the FPC.

2) Do something similar to what we did with tiOPF and Interfaces
support. Implement Observer in the base classes. IFDEF its
functionality (this should pretty much cover one line of code only).
Enable the IFDEF by default. That way everybody else can benefit from
the new Observer support by default. Marco can then disable the IFDEF
in his own copy of FPC and live in compatibility world (population 1).
