I’m studying the outline of PR [28970
Rationale: This is "non-robust 1-parent-1-child package relay" which is immediately useful.
A couple of questions:
What exactly does non-robust mean in this context? What risks do I take on if I just rely on the normal CPFP-based flow? Are there situations where my parent transaction could still fail to confirm?
From the 28.0 release notes, it looks like Bitcoin Core 28.0 will automatically form a 1p1c package when I broadcast transactions via sendrawtransaction. Is that correct, or do I need to use the package relay APIs explicitly?
