My thoughts exactly. Done.

I'll think about that. Any such dangerous erase extra stuff
should certainly not be a default behavior, when someone has gone
through the effort to specify exactly the address range they want
to erase!

That's more work than I want to do for now, but it would be a
more general solution.
My conclusion from looking at that code is that the intelligence

The following patch should help in at least some cases;
it doesn't insert sector
What flash erase address range does is to a) identify sectors
within an address range b) erase all those sectors. There is
certainly nothing broken about a) and if I wanted to do b) then
there is nothing broken about that either.
At most, there could be a non-default option to flash erase_address
I do think it might be useful to print actual address
ranges erased in some reasonably terse and non
warning format.
This would help the user learn what flash address_range
/ write_image erase is doing and should cover your concern
as well, I think.

If it's going to be erasing data beyond what it was told
to erase, we deserve at the very least a warning.
That's pretty

An alternative would be to add an option that is disabled by
default that will check that the address range matches sector
boundaries. This is incompatible, but perhaps a better way to
go?
This would be along the lines of the options we have for flash
write_image.
flash erase_address force
Ouch.
This is a bit worse than I thought.
This breaks flash write_image as well.
Flash write_image will first erase all sectors in address ranges of
all segments to be written, then it will write all segments.
