Haha if you have been around for a while you would know that full blocks are due to massive microtx and dust spam instigated by some shady elements of crypto society during major uptrends. It happened November, 2015, June and August, 2016 and is apparently happening again. I'm sure mempool will be naturally cleaned till the end of the current activation period.
I've been around long enough to see devs delay payments for nearly a week (last month and the month before, if memory serves) and not even try to push until the mempool was under 10k, so 70-90k doesn't provide much hope. 
) as the effort to reward ratio is too high.
The result was essentially being told that nothing will ever change because "it works now" and "there's no reason to reinvent the wheel".
