I think I can offer one explanation why it now, the way it is.
Of-course, whether it's the right way to do things or needs to change,
needs to be determined by this design discussion.

During the initial stages of the development of this feature, the
select and deselect operations were quite slow, because every
select/deselect change was being written to the journal entry metadata.
This made it essential to show progress of both select/deselect as the
operation often took several seconds (in some cases minutes)

However, later the operation was sped up significantly to just a few
seconds even in case of many entries (because the select/deselect info
was just being stored in-memory). So this may very well be a remnant
of the way development for this feature took place.

Just my 2 cents.
