AFAIK the rationale for a sealed class is that it can not be extended.
In big shops that has an advantage in maintaining code. Also third
parties can "lock" their code.
f.e.:
TDoNotTouchMe = class sealed (TMyTouchableClass);
Means that if you use the former you cannot break code, if you use the
latter (the parent) you can still extend your hierarchy.
Correct me if we are wrong ;)
We use it a lot after codereview and final checkin the production branches.
For us it means: "you must have a very good reason to touch it"
