More pins is not safer, but just increases the risk of a single failed pin without mitigating the possible damage. Pins with good contact are safer than those without.

Pulling 50A through a connector of that size or smaller is in itself not an issue. As mentioned elsewhere, powerpole is smaller than an 8-pin connector and handles 55A at 10000 cycles without a hitch (even hot plug at 30A for hundreds of cycles). That this connector only does 40 cycles before breaking is caused only by it being poorly made or a poor design (e.g. relying on interference fit of contacts rather than true spring loading), and has nothing at all to do with the size.

The current plug is an ugly and cheap connector, so I don’t see aesthetics as a valid argument.
