For me (and not only for me) it is a vital point of having the freedom of choice to solo mine on a bitcoind or a pool.
If all trustfull pools/solopools went away, I still got the opertunity to solo mine directly to core.
End of story
So to me it seems like you are the equivalent to a Dooms Day Prepper for the Bitcoin world? I don't mean that to come off as an attack, but this will be my 9th year on this forum and there are still trustworthy pools/solo pools you can mine on. What I do notice though is you follow any project Kano is involved with because YOU want something changed. I am sure like you said there are others but it's YOU that follows into Sidehack's product releases talking about how it's not truly something. Which as of right now and for the forseeable future it is as I do not see pools disappearing for awhile, and by the time they do this hardware will be the equiv to running an Antminer U1 on a modern day pool.
Another analogy when it comes to the end of the pools, would be again comparing a person watching for the end of the world and prepping for it. It would be the same as calling every gun manufacturer and complaining that even though they only make the firearm that nobody will be able to make bullets for it if the world were to come to an end. You are literally worried about something that isn't a problem and have been all over any Gekkoscience release because Kano is involved.
So how about you set up your own stratum server and run instead of worrying about mining directly to Bitcoin core? OR, how about you pay to have your own developer right a new miner specifically for people like you and the others you mention and then you don't have to follow people like Kano and Sidehack constantly trying to tell people that it's not a solo miner because in the future you can't just mine directly to core?
