Quite frankly, I think they should do it sooner or later, no pressure needed.
As I have stated here:
Privacy market is becoming a huge opportunity and at the end of the day, people are becoming sick of google and fb. Projects like librem5, /e/,… are grabbing the attention, and I think that sailfish has the best story of them all. There are some rough edges to be polished but I am very satisfied with 4.0.1 on xperia 10 plus (and I have moved to it from my own rom that had all that I need or want. Now they have to scale up and support as many devices as possible. If they will fail to do it, someone else will lead the market.
