Your boats, your rules. That said, you would be in more difficulty today had you encountered a relief valve that failed to blow off...
By their nature, blow off valves should
vent at a pressure higher than the recommended working pressure of the tubes. Filling to a known pressure (even if it is slightly higher than the working pressure) seems safer than relying on a crude vent to avert a disaster.
