You are right.
syzbot email only MAY be correct :)
But for me the point re email still stands: why are we even spending
time discussing this? Why are there such extensions with MAY status?
If one doesn't care if the received with recover the original message
or not, why caring adding/specifying these "format=flowed;
Obviously somebody in the middle got confused about these flowed/delsp
as well and either assumed that they are MUST or assumed that
preserving precise text for emails is just never important...

I don't see how it's possible to make it more forgiving without also
appending unrelated text that happened to be on subsequent lines to
patch titles and breaking everything the other way.
I added one partial escape hatch in the form of:
This allows to send slightly longer titles. This is still parsable as
we know that commit titles can't be empty.
Regarding another mail agent: again this only proves the point for me:
this is what tool developers are forced to be spending their resources
on, rather then working on adding more useful features...
I don't even know where to start re switching mail transport; how much
the switch will cost? what are other transport costs in the long term
maintenance? what are their problems?
