I think it is important to recognise that seeds are not inert, dead things. They sense the daylength around them, and so may prepare to germinate at the appropriate time. What does a thermostatically controlled fridge do to them?
I store all my seeds (in Los Angeles) at room temperature until the appropriate season arrives - including those from overseas - with good results. Refrigeration is a crutch for those with limited time or space, and shouldn't concern those people who can sow their seeds within 12 months of receipt, assuming fresh supply (that is anther question).
Seeds that I might store for 10 years? - well, they should either be thrown out into the yard or given away, since they are clearly of no importance!

In accordance with this principle, I usually let
spring-harvested seeds sit around a few months before refrigeration. Once
in the ice box they stay there until planting time, which can be 10+ years.
N.b.: While viability is reduced over any longer period of time, even a low
percentage germination rate can be adequate. A few sprouts out of 100 seeds
sown of Lachenalia pusilla over 10 years old is gratifying.
