TFileStream is inherited from TObject, which has a Create without

No, I don't think so. If you want users to use the original constructor as
well you'd need to declare yours as "overload". If it would be possible to
call TFileStream.Create without parameters then the instance would be in an
inconsistent state, so only calling the constructor with arguments should
be possible (which is the case for TFileStream.

So this is definitely by design.
