gross DNF bandwidth inefficiency if filesystem space limited

[Felix Miata]

# dnf upgrade
(dnf nearly exhausts freespace downloading all packages before installing any
packages)
dnf then reports package xxx needs ##MB on / filesystem and exits without
doing any installing
dnf all deletes downloaded packages
# dnf upgrade (package subset, e.g. dnf* rpm* a* b* c* d* e* f* x* y* z*)
dnf downloads needed packages previously downloaded but later deleted, then
installs downloaded packages
# dnf upgrade
dnf downloads needed packages previously downloaded but later deleted, then
installs downloaded packages

Is the above deletion of freshly downloaded packages (wasted time, wasted
bandwidth) known or expected?
