It could never be that high. With a lower ‘k’ (desired by quite some people) at the same time, pools would only consist of pledge. Such a setup would not be rational at all. To me, it displays the fear from change a little bit.
Personally, I’d not be advocating for gigantic changes once a year, but rather smaller adjustments to parameters on a regular basis. Maybe steps of 10% max. every five epochs or so - as an ongoing, continuous process. Also, limiting the rate of change stabilizes systems, too. Adjustments would be way smaller disturbances to the network at the same time. And less risky - same argumentation as with ‘d’, which seems to be widely accepted. Also, it would be a signal, that so the so called “community” can actually be part of this - way before Voltaire might (!) be functional at some - still speculative - point in time next year.
With the current setup, most operators will never be able to prove, they can offer stable operation and rewards. There’s no inherent incentive to delegate to any pool other than the “big” ones. Which is completely fine, if you think, this is the way forward.
To me, praising “the gods of marketing” is like telling smaller persons in the stadium to stand up to see better. In the end, the root issue will not be solved, it will even become worse: Everybody will be standing to reach the previous steady state again - and all this effort for nothing, people might be pissed if it was not a rock concert situation ;-). Instead, changing the “parameters” would have been advantageous for all viewers in the first place: the person in front could have been more considerate, a different distribution of people would have been possible, one could leave empty spaces for smaller people, etc. This is just an example.
Or transferred to pool operators: Everybody will busy advertising their asses off, redirecting resources away from actual network improvements, pool operations, bug reporting, more hostility instead of helping each other, discussing. They would be busy marketing, spamming ticker symbols everywhere, “we are the greatest”, producing “news” videos (nobody watches anymore, because everybody tells the same anyway) etc.
In terms of variable fees, this race to he bottom has begun. Or actually… it finished already at 0%. And it did change… nothing at all.
The current setup does fail to incentivice anything else than the current distribution of power (=control over delegated stake). We are way into the steady state already.
Leaving for the outside, non imaginary, world - have a nice day
