No. MTX defines 64.71.152.40 as a legitimate transmitting mail server,
regardless of the domain in the envelope from, From: header, etc..
Popular misconception, it seems.
The SPF record above says that a host using "panic.chaosreigns.com" in
HELO should not be allowed to send mail unless it has the IP address
64.71.152.40, regardless of the domain in the envelope from, From:
header, etc..
That's not exactly the same as your MTX scheme, but it has similar
results when combined with a FCDNS check on HELO (providing your scheme
is universally adopted).
If you're serious about your proposal, you should explain (in your
documentation) in what important way it differs from SPF as used against
HELO and other similar schemes, and why it is better.
