Are you sure? It's also a dust amount, miners also reject those. I have seen many <1 sat/vB be confirmed.

Dust amount for P2WPKH is 294 sats and sub 1 sat/vB transactions are getting confirmed everyday although not 0.1 sat/vB.

The dust limit is 297 is it not?{MinRelayTxFee (68+31)}*3= 297 not 294...
