Of course, not for individual rockets on individual flights (but self-repairing would be way cool!).
But Anti-Fragility as you define it definitely should be a goal for their overall organization and system of building and operating the fleet.
Each issue or incident should feedback into the engineering of new units and updating of existing units so that they are improved, stronger, less likely to create issues, more able to handle issues, etc. on each iteration. This actually seems to be the case at SpaceX, including this incident.
Oh yes, that is an excellent observation. The components themselves cannot be antifragile, but the development process certainly can.
Thinking about that, an important feature of that antifragility is not to risk human lives during the process if that risk can be avoided. Even though space exploration is inherently risky, any actual fatality is a huge setback.

Or, am I missing something?
