Additionally, with floating point processing i'd like to see the user working
with just 'colors' -- and be relieved from having to choose a working space.
I wonder what the problems of ultra-wide gamut color space are (due to
virtual colors etc.). I'd be grateful for any pointers.

.. i'll hope for some magic that someone chimes in to make it happen ;)
However, there are several options to lessen the required coding effort
for import handling *). The most radical of which is to use the classic
pop-up dialog, together with a corresponding prefs item:
"Ask on bitmap import: always/never/if in doubt".
The other sections of the proposal can stay pretty much the same.
If this variant sounds reasonably close to a minimal strategy, i can work
out the details, just let me know if that makes sense ;)
In comparison with the current behaviour, this solution gives better defaults
to support both a color-managed primary workflow and the secondary workflow,
which moreover may be unmanaged -- without one having to dive into the preferences.

*) There are two more variants which should require less coding than
the on-canvas approach and still offer smooth workflows:
Adjusting the color space conversion boils down to two steps: 1) undo the last import
and 2) re-do with the new parameters, so my uneducated guess is that the bitmap to be
imported could be pushed on the undo stack...
Variant 1: buttons in the viewport corner instead of an attachment to the new layer(s):
