          one simple solution would be to include the prefix here as well

qs/lib/stringify.js

Lines 123 to 129 in 981ce09

	if (isNonNullishPrimitive(obj) || utils.isBuffer(obj)) {
	if (encoder) {
	var keyValue = encodeValuesOnly ? prefix : encoder(prefix, defaults.encoder, charset, 'key', format);
	return [formatter(keyValue) + '=' + formatter(encoder(obj, defaults.encoder, charset, 'value', format))];
	}
	return [formatter(prefix) + '=' + formatter(String(obj))];
	}

to this:

    if (isNonNullishPrimitive(obj) || utils.isBuffer(obj)) {
        if (encoder) {
            var keyValue = encodeValuesOnly ? prefix : encoder(prefix, defaults.encoder, charset, 'key',  format, undefined);
            return [formatter(keyValue) + '=' + formatter(encoder(obj, defaults.encoder, charset, 'value', format, prefix))];
        }
        return [formatter(prefix) + '=' + formatter(String(obj))];
    }

without introducing any breaking changes to the library
