First thanks for your detailed analysis. I have looked into this problem
some time ago as well and I found a website, which documents this
behaviour here:

(German, sorry)
The parameters passed for these delphi exceptions are different and they
are only to be handled by the delphi exception handler, which is
triggered after the first chance exception and should display a message
box or something and terminate the program.
Your suggestion to "hack" this into reactos seems reasonable, and I
wouldn't consider this a hack, but rather a feature.
The best way to handle this is before it get's forwarded to the kernel
debugger, so probably in KiDipatchException.
It just has to make sure that the user mode exception handler receives
the original parameters.

Timo
