Without dumping, Emacs startup would be comparable to
temacs -l loadup.  That takes almost 2 minutes on my machine.
emacs -Q takes about 3 seconds.

Maybe you can make it faster than that.
Perhaps half of the files would not need to be loaded at startup.
It would not need to do GC as much as it does.
Nonetheless it will be much slower than emacs -Q is now.

Thus, I am strongly opposed to this change.
Perhaps it would be ok, considering only fast machines.
But Emacs has to be good on slower machines too.

I'm not against eliminating dumping if and when the benefits of
dumping are truly no longer needed.  If you can make the initial
loading 20 times as fast as temacs -l loadup, it would be just a small
annoyance.
