My intelligence test came back negative.
During the start-up transient, the resistor could briefly see as much as 50V. A 1 ohm part would pass 50A, so the instantaneous dissipation could reach 2,500W!!! Now all resistor constructions can withstand much higher powers for a short period, but that is a lot of stress.
Using a decent sized part means it will have enough mass to not heat up too far during the start-up pulse.
