Neutrino is very controversial, and NOT less trustful than bloom filters.
It also uses significantly more bandwidth.

It seems a better approach is to add Stratum (Electrum) support, and to limit 
usage of all pseudo-SPV protocols to trusted peers.

Eric Lombrozo added segwit support. While it was never reviewed for Core, it 
has been included and supported in Knots since v0.15.1. As I understand it, 
his mSIGNA wallet also makes usage of the feature.
