`message-view-patch-regex`'s wrong default value

[titibandit]

When following the tutorial over at https://git-send-email.io/, you will send a patch like so:

---
 thibaut | 1 +
 1 file changed, 1 insertion(+)
 create mode 100644 thibaut

diff --git a/thibaut b/thibaut
new file mode 100644
index 0000000..7fbef93
--- /dev/null
+++ b/thibaut
@@ -0,0 +1 @@
+I have successfully used git send-email!
\ No newline at end of file
-- 
2.45.0

This patch fails to trigger message-view-patch-want-treatment, because the @@ ... @@ line is formed with only 3 numbers instead of the 4 expected by message-view-patch-regex. I guess that's because this is a new file so there is no hunk context.

I've modified message-view-patch-regex with (message-view-patch-regex '("^@@ -[0-9]+,[0-9]+ \\+[0-9]+\\(,[0-9]+\\)? @@")) and that works now.
But this could be the new default?
Cheers
