It also uses significantly more bandwidth. It seems a better approach is to add Stratum (Electrum) support, and to lim= it=20 usage of all pseudo-SPV protocols to trusted peers. > The fact that nobody cared about extending it for SW may also underline t= hat > BIP37 is seen as a conceptual mistake and/or "low interest in further > extensions=E2=80=9C.=20 Eric Lombrozo added segwit support. While it was never reviewed for Core, i= t=20 has been included and supported in Knots since v0.15.1. As I understand it,= =20 his mSIGNA wallet also makes usage of the feature. Luke
