Forsh, I was flippant a little, what I meant is one starts with analyzing halachic concepts and see if they are applicable before going further. Halachik reasons for dealy is informing relatives, publicizing the event. One is praiseworthy speeding up a burial, unless it is for a parent when it is not proper. considering that T’Ch is a teacher for all and in this case, clearly participation of those who want to come requires preparation, there is reglaim l’davar – and this is what I would start discussing if I were bothered with the issue like you are.
An interesting note: Moses Mendelshon corresponded with R Yaakov Emden regarding possibly abolishing speedy burials. A local Duke ordered everyone to keep bodies for several days after there were cases of live people taken to graves. Kahal asked MM to intervene and he helped to stop the decree, but later discussed with YE. YE’s position seemingly was that Chevra Kadisha pays attention and would not bury live people, like goyim might.
