Recently I prepared some problems and wrote a contest proposal which was submitted on $10^{th} July$. However, I haven't written any contests before, so I have some questions. Really appreciated if you can answer them.

$1$. How long does it take to get feedback from coordinators in average?

Today is $18^{th} July$. $8$ days has passed. It said that I will receive feedback in $2$~$14$ days, but I'm still worried. Although I believe the queue is not as big as two years ago, I'm afraid that I'll not be avaliable if the waiting time is too long （more than $1$ month)

$2$. Will I get notified if someone commented on my proposal?

$3$. Does Polygon support the $64$-bit version of C++17?

I didn't find it when I choose the language. One of my problems requires a checker which can compute even the number doesn't fit in $64$-bit integer, but under $128$-bit integer.

C++17 64bit supports __int128, which is the perfect one to use. However, if Polygon doesn't support that, I have to lower the constraints or manually implement bigint.

If you submit in C++ and your code is getting WA or RE, you won't receive the verdict immediately, and your code will run in diagnostics mode very slowly.

Usually I don't want to waste time in that run, so in the past I chose 64-bit C++17 in order to get rid of it.

But for now, 64-bit C++17 will also run in diagnostics mode if we gets WA/RE. I don't mean that's bad, but is there any way to disable diagnostics run (only for myself)? If not, then can there be a function like this?

I think there can also be a way, which is if we get WA/RE, display the verdict immediately, and then silently run the diagnostics. MikeMirzayanov please consider about it, really thanks. OK, now diagnostic works exactly like this. Really thanks for your hardwork, codeforces

There are plenty of submissions with "In queue" verdict, while no submission is running on tests.

Will it affect the contest today?Hope it won't affect :(

UPD:Judging system is back now.

1. "During normal rounds, hacks only related to me(being a hacker or as a defender) will be shown." Is it right?

2. Why some people can hack other's code even not in the hacking time(During the contest in normal rounds, During the hacking-phase in edu/div.3) ? I'm curious about this. Is it intended or a glitch? Although, hacked solutions will keep AC verdict

I'm not experienced in hacking, so could anyone answer these questions?
