[concours] E-type - Safety Question Part 2

I would also like to fit earless hubs to the car at some point. The eared
spinners are rather dangerous. Would these qualify under safety mods and,
if so, would I then add the spinner removal tool to the tool kit?

This is one that would obviously be in the “nice” category, but I’m on a
roll with these questions and am making up shopping lists…
