it looks like that in version of 28 polkadot was change that extrinsics are by default transactional.
Before that we used attribute
#[transactional] for specific extrinsic in order to have transactional extrinsics.
But now it looks like that all extrinsic by default are transactional and in our case we do not want to have all the extrinsics transactional.
Is there attribute in order to annotate extrinsic as non-transactional ?
