From an idealist perspective I would like such devices to submit

not sure that will fly as there seems to be a lot of mindshare in
that world around submitting mail using port 25. More generally,
there's a lot of preference for using as little configuration as
possible, especially per-device configuration.
It's fairly common for nascent efforts to seek ways to simplify their
work and operation, on the claim that they have a simpler environment
and won't (ever) need the additional mechanisms. In those early days,
the appeal of the simplifications is understandably strong and even
seems reasonable, within their immediate framework. However their
assessment of the future is almost always wrong.
These people do not see their efforts as "nascent". Devices like
these have existed for decades. Though they're starting to become much
more common, due both to the increasing capability of low-cost hardware
(think raspberry pi, beaglebone, etc) and the Linux ecosystem with all
of the code available for reuse.
