I don't personally consider this bad attitude, as you had some technical
arguments in favor of your approach. I balanced the various advantages
and drawbacks of both approaches, and judged that, although I would have
still prefered us to use observers, your approach was an acceptable
temporary compromise (temporary meaning until annotation are removed).
One of the elements on which I based my judgement was the fact that
I understood that this was going to be the only new annotation.

My perspective on this is that I would like to see as little effort
spent on annotations as possible. If you think the change is going
to make GDB better, then perhaps your suggestion is worth it. If it's
just to reduce the pressure to remove annotations from GDB, then
I think we need to look at the maintenance cost of keeping them in.
If possible, I'd rather remove them all in one go rather than remove
some of them in exchange for the new ones being added.

I don't know the annotations well enough to know what the actual impact
might be.  They might make GDB better.  But I'm quite concerned about
the front ends out there that might be relying on some the annotations
that are proposed to be removed.
