I don't see the difference.  One man's feature is another's
peculiarity.

Btw, is this division described anywhere?

If the issue at hand is just between the architecture and the target,
then why you had to touch breakpoint.[ch] in your patch?  AFAIK,
breakpoint.c belongs to the higher-level GDB layer, above both the
target and the architecture, isn't that so?
