I am speaking for myself (I am an engineer at ECC, not an official representative of their position), so I will only restate what information is already available (like above). With that in mind:
The transparency report tells you that this was 62% of monthly operating costs in the second half of 2018, which is $434k. Thus a reasonable guess would be that of the 1M figure, somewhere between $620k and $730k of that would be wages (62% assuming same ratio, 73% assuming the increased budget was solely used on wages). Neither figure will be accurate, of course.
Given that a full 4 pages of the 2018H2 transparency report detailed this information, I think it’s reasonable to assume that future reports would as well.
See @nathan-at-least’s talk at Zcon1 for targets covering the first couple of years.
Reminding you again that I am speaking for myself, not ECC: I agree with the Foundation’s position on this. There may be some ZIPs that turn out to be technically unworkable, and others that are incompatible with each other. Beyond that, all current proposals are collected in a central thread (thanks @sonya for maintaining it!) that is easy for anyone with a vested interest in the outcome to find and follow.
