Just a reminder that if the BTC or BCH price increases, so do the fees by the same multiplier. $5 fees at 5,000 become $50 at $50,000. .3 cents only turns into 30 cents at the same rate.
And maybe some miners will accept lowers fees. But indeed it will increase fees on the short term
The thing I'm unsure is the 1sat/b for 0confs ..
I don't know if we can easily lower that limit. Because if you have to update your node to lower that limit then not everyone will do it and .1 sats/b will propagate less easily than 1
