Segwit included a capacity increase, but fees are still so low that there's been little pressure to adopt it. I think we should let people adopt Segwit before pushing for more.
Letting people adopt Segwit isn't easy when a handful of largest entities in crypto aren't going to adopt it. Blockchain.com alone could contribute an easy 10% increase in Segwit adoption if they stop sucking off Roger and Jihan. The sad truth is that it will probably never happen. In the same camp we have BitPay that will probably never adopt Segwit.
The only relatively large short term bump in adoption can be expected to come from Binance when they finally switch over, but even then I doubt that we will leave the 50% adoption mark behind for ever. The average adoption percentage currently is ~40% which is shockingly low. Litecoin is doing way better in that regard, and they don't have to scale at all.
