and if not present, point out the problem, and request re-submit.
there was plenty of time to ask for clarification.

i can't wait to see if this changed the outcome or not. if it did, it
creates a very uncomfortable situation.

this topic also came up a while ago. how do we know what kind of
hardware will we have in ten years? overoptimizing to one
architecture, against some other architectures can become obsolete
really fast.

can you cite me an example? i'm almost sure that for example estream
did not do that.
