Allowing intra-block chained transactions has some problems:
Makes it difficult to parallelize the validation of transactions in a block.
The validation logic itself is much more complex than it should, because we can't just rely on what's in the UTXOs set to know which prevouts are valid or not.
The main reason why they exist is that Bitcoin's blocks are created every 10 minutes, in our case we create blocks every 8 seconds.
Describe the solution you'd like
Stop allowing intra-block chained transactions, remove all the code supporting them, simplifying production & testing code.
Describe alternatives you've considered
No alternatives considered.
Additional context
Removing intra-block chained transactions would also help to implement things like the "compact transactions" proposed in #474 .
It will be harder to merge changes from Bitcoin into Unit-e if we follow this path.
