Could /etc/profile please also add /cygdrive/c/Windows/Sysnative to
the end of the PATH?

It doesn't add any other Windows folders so why this one.
### Summary
Why should Cygwin add Sysnative to $PATH? As a workaround for
Microsoft's failure to add Sysnative to %PATH%.
You have the option to add SysNative to your system or user PATH under
Windows, although that would best be done in your login script.
### Full explanation
Cygwin imports the Windows %PATH% variable at startup.
It would be ideal if Microsoft would add Sysnative to the default
Windows %PATH%. Such a change would help Cygwin users and others.
But I doubt that Microsoft will make this change.
Therefore, I am suggesting that Cygwin work around Microsoft's
omission. My suggested workaround is for Cygwin to add Sysnative to
its own $PATH, automatically.
Cygwin starts with Cygwin paths /usr/bin:/bin and everything else is
up to you.
You may add to your Cygwin PATH in your shell profile with code that
switches depending on the existence of SysWOW64 and SysNative: cygpath
-F 37 gives your application sysdir path, and cygpath -F 41 gives your
x86 sysdir if there is one:

https://docs.microsoft.com/en-ca/windows/win32/shell/knownfolderid
and please note that SysNative appears nowhere!
That's because Sysnative is not a known folder. It is rather unknown
just because it is virtual :)
And that is the problem I tried to address. In cygwin32, you can `cd
$WINDIR/Sysnative` but you wouldn't see the folder. For tools like ls or
find it simply does not exist, while obviously it exists somehow and can
be used in PATH.
