Btw, thank you, this bit of history indeed is interesting. During whole
discussion I had a question on the back of my mind: how this
"distribute pre-built elc in tarballs" idea initially came to be. I
mean, it's kind of nice from POV of saving a bit of energy around the
world on CI machines, but I don't see much beyond that. Building elc
files is not *that* bad for elc distribution to be strictly necessary.

Now that you told this, I realize it's just a solution to a problem
from 25 years old back, from times when that actually was a problem.
