Ok, but ESC[c is a stock vt100 sequence.  Admittedly, I have no idea if
there are other terminals out there which use this sequence at startup,
too...

Per the vt100 documentation, the response is supposed to be

  ESC [ ? 1 ; Ps c

with Ps being a character in the range 0 - 7.

Just being curious, what are mintty and OpenConsole returning?

Weird.  But Windows on AArch64 supports a x86_64 emulation, iiuc.

"aarch64" :)

Oh, wow!  Looks like fixes to build WIL on MingW have been merged just a
couple of hours ago.
