Destroying required components in editor

While in the Editor, I want to be able to call destroy on components. In this situation, two things can happen:

A) That component is required by some other components. In that case, I want to print some message saying that the component can't be removed.

B) That component isn't required by anything else, so it can be safely removed.

After destroying the component, I also want to be able to undo the operation.

Here's the thing: if I use DestroyImmediate, it will work just fine (both A and B), except that I cannot undo the operation. To be able to undo it, I should call Undo.DestroyObjectImmediate. That, however, destroys it without checking if it is required by any other component; which breaks Unity after trying to undo the operation.

I had considered using reflection to make the check myself, which wouldn't be that hard; I just wanted to know if there's any better way around this.

Also, I'm currently using 5.3.4f1

Thanks a lot!
