death and rituals

hi everyone, i hope ya’ll are doing well. i had a question around modern interpretation of death rituals in Zoroastrian religion.

i understand that since land and fire are considered pure sacred elements, they can’t be defiled by impurity of dead body and hence tower of silences were created so the bodies could be consumed by vultures and other birds/animals so even in death, a human could be useful to nature.

my question is: if lets say, one donates their body to science/medical research/school post their death, the person’s body is still being useful after they’re gone, would this be considered true to the spirit of the religion?

please let me know your thoughts.
