It seems that my message was misinterpreted, so let me clarify a few things.
I'm not saying that increasing the size of the binary is a bad thing,
specially if there are lots of improvements that caused this increase.
My message was just a note to be sure that bandwidth availability is not
forgotten, as it's fairly easy (I'm guilty of that myself) to take for granted
that downloads will always be fast and hassle free.
Concerning the environments where it matters, I currently live in South Africa,
and even if things are improving fast in terms of bandwidth availability,
there is still a long way for people to get fast access at their houses for a
fee that is accessible. So I'd say that environments where the size of
binaries has no impact are the clear minority here.
That said, as I've raised the issue I wanted, and you are aware of it, I do not
see a reason to increase the size of this thread.
