I can tell you this, if I ran a multipool and a coin's Dev team asked me to quit while they planned an upgrade, I would certainly comply. For now, we could just ask them to drop NLG until a long term solution is found.
Just my 2 cents....
A good change miners will return if Clever drop NLG for a while.
And... if 50 miners all add there 2 cents we have 1 nice Guilder!
