I would politely suggest that anyone interested in the K parameter at all focus their energy on it continuing to have some actual meaning. According to the design architects, the K parameter is supposed to represent the upper limit on the fraction of total Ada delegated to any single operator.

There is absolutely no point in increasing the value of K if it is consider good behaviour for everyone to run multiple pools. See CF’s proposed delegation changes in this thread: Cardano Foundation Updates Delegation Strategy

Let’s try to reinforce the meaning of the K parameter before we seek to change it. I think it might be better to reduce K so that it is in-line with whatever the value CF now thinks is OK for the proportion of total stake delegated to one operator.
