Strange that over the years no one has put asynchronous Order functions into the MT4 kodobase.
How is it? Orders from different terminals?

Chartow.
Charts.
This option, unfortunately, only works for one symbol at a time.

I would call them multi-threaded but synchronous because they wait for a response from the server anyway. There was such a product in the Market. You can search for it.

Technically, it is not difficult to create such a scalable system of auxiliary Expert Advisors to send orders, but is it worth it?
After all, there is only one trade flow anyway. While one order from one EA is being processed, IsTradeContextBusy will return true and the next ("parallel") orders will hang in the queue.

Not so. IsTradeContextBusy will return true if 9 orders are sent before at least one of them is processed. Checked. 8 - yes, everything works. Nine in parallel - yes, "thread busy".

Is there a link to some official source of information? Then, the returned value doesn't guarantee anything, even if the behavior is exactly the same - most likely, it means that there is a buffer for 8 orders but there is still one thread sending them to the server.

The thread is the same for one EA. Eight EAs in an account will work without interfering with each other.
I find it strange that you still don't know this. It has been said many times, including by Renat.

When trading the same portfolio, we need such asynchrony like air. Since Expert Advisors/Scripts can be launched on pure MQL4 and new charts can be opened for them, we just need to write a literate biblue for MT4 once - connect it to the source code in one line and all Order-functions become asynchronous, with OnTrade through CustomEvent and when the Expert Advisor starts, the eight universal Expert Advisors will be automatically loaded in the background.
