Yeah! I strongly agree with the difficulty in doing this (and that EA is a unique fundraising environment with donors with a weirdly high willingness to change their mind). But, I think one under-appreciated fact is that if charities really strongly differ in cost-effectiveness, non-cost-effectiveness-oriented donation advising for non-EA donors might accidentally be doing tons of good (e.g. by making minor shifts in how funds are used that end up having larger changes in size of effect than the difference in cost-effectiveness between EA interventions)
