"bitmap oversample" setting used for both view and bitmap export, should not

I agree with you. This bug has been here for so long...

> In any case using this setting for both view and final export makes me go change this every time I want to export.

I run into same problem. My workaround is to keep default settings of 2x2 (for quick viewing) but export with high dpi.
I have a short Makefile that postprocesses the bitmap using ImageMagick convert to intended dpi, effectively doing the missing oversampling. It's a little slow but only needs to type "make" on every export.

Makefile :
# example assuming image exported as my_image_from_inkscape.png
default : my_image_antialiased.png
# 25% for 4x4 oversampling over the 2x2 made by inkscape roughly approximates a 8x8
%_antialiased.png: %_from_inkscape.png
 convert -verbose -geometry 25% $< $@
# space above is actually a tab char, as required by make

I fully agree that settings for viewing and for export should be decorrelated.

 > I suggest disregarding this setting for exports, similarly how this is done for gaussian blur filter quality setting.

> I would recommend using the best rendering for final exports, and give an option/command line parameter to override. 8x8 gives very decent results, so maybe 16x16 is an overkill.

Agreed : use best quality by default, let user override.

You are right to compare with blur effects. The associated preference panel clearly states that it's a display setting.

Closing - the report is obsolete: the setting 'Oversample bitmaps' no longer exists in Inkscape >= 0.91.
