IMO, the medium term solution for all export-workflow problems is to have
an in-gimp way to manipulate a set of transformations to be applied to an image
on export.

Thinking on an UI for this now is up to us - so, why not bring the idea
to the list?

Currently, actually most export plug-ins do perform a
image-duplicate, image-flatten (or merge visible layers) and save
the resulting layer. Indexed formats do a "image-duplicate,
image-flatten, image-convert-to-indexed" sequence.

Having this in an UI would allow one to have several presets like:
image duplicate, image-resize(max-width: N, preserve-aspect: True),
image-sharpen, image-flatten, image-convert-to-precision(8bpp),
gimp-pause-for-review, export-to-desired-file-format  )

That would allow presets for example, that could at once save for the
various icon-sizes needed for
icons in mobile projects bound to a single keystroke. (and having  a
"mark as clean" node available for these presets
could also give an option to the "I do only jpeg exports" shouters)
