Let's say you are approaching a uncontrolled airport with overcast at 1500

this is why there are more than one radio in most aircraft and in virtually
all aircraft that fly IFR regularly?

I don't know the original purpose for two radios, but it cannot be
that, because there will be no VFR pilots (legally) in the pattern
with an overcast at 1500 feet.

While 1 radio is legal ( as is no radio) its not very uncommon. When
approaching an uncontrolled field IFR any reasonable pilot will have
CTAF dialed in #2 and listening long before ATC releases him, so he
understands what is going on in the pattern.
