I don't. But what really matters is the static vs runtime cost, see
e.g the thread I created. The ratio will be far more similar across
arches.

No one has told me what is interesting, and in the last 6 months, I
have not seen a commit that I find interesting either to get an idea
of what can be done for the project. This is nothing against the
authors, who are all fantastic people, just my opinion. I am here to
serve the project, not because I find it "interesting", but because it
lacks manpower, and I find its goals worthy.
This philosophy has already been mentioned:
