Agree that we should minimize as much arbitrary data as possible but, as I thought, the transaction is used to provide functionality.

Now, whether it is the most efficient method to achieve such functionality, that is another matter entirely.

It would be nice if they could add more user metadata into the operation to provide more useful information as a sort of compensation for required overhead in each block.

I mean cryptographic signing operations are relatively resource intensive so may as well try to add a bit more usefulness.

Thanks for getting my hamster wheel spinning'
