I guess the thing to say is "Not untypical". I dont know if the original Austin axles commonly fail like this but the very hard through hardened Regent ones seem prone. It is remarkable that the half moon seems to steer the cracks from progressing traversely.
The diff on my car was changed but at 110,000 miles the original axles are intact with small cracks only detectable with fluid. Never lapped and not regularly retightened.
I have a collection of such axles from derelict cars and diffs. I dont know what proportion fail transversely but as the cars are rendered immobile less likely to come across.
If selling the car, relieve the centre of the taper slightly and reassemble very tight!
