No. There is no need to install a full 15A or 20A connector when the
appliance only needs under 5 A.

There are plenty more that don't.

They are approved for the rating stamped on by the maufacturer. 20A
fittings use the same prongs as 15A, but in a different configuration.
I'd have to guess they may handle current in the 20A+ range.
