That first clip is actually from my podcast. What she's talking about there is things like improvements to relay that would help L2's like lightning, while being mindful of DoS risks and pinning attack vectors.
Some of that work DID get in and you can see here L2/Lightning developers (
@acinq_co @blockstream @lightning and
@spiral_xyz ) all speaking positively on her work in how it helped them.
And people who want to see the bit just before/after the clip, see full podcast here
