Just my two cents:
+1 to leave it as it is
reasoning: I would always expect the current behaviour; a virtual field
is - well - virtual, I can redo it after processing (BTW it would be
good if it was savable in a qml file) and I can join to the result, too.
No need to carry unnecessary fields from joined layers along.
Plus, as stated in the discussion, GRASS/SAGA/ogr won't keep these
fields anyway, to implement it for QGIS algs only would result in
inconsistent outputs

Hi all,
and sorry for cross-posting.
When cleaning Processing bug queue I found issue [0] about preserving
joined fields in Procesing outputs. Before implementing this I want to hear
opinions, does it makes sense at all or better to leave things as is: output
layer contains only provider (non-joined, not virtual) fields from input layer?
Thanks
