The fact is, whatever that person may think, sooner or later, the need
for further modification may indeed arise.
At that point, that person will answer the question with "I would have
preferred that other form, but I discarded it, hence I prefer this one,
among the ones I kept around..."

It's clear that they *will have* to prefer a compressed form, as soon
as they face the need to make (unforeseen) further modifications...

I was not clear, sorry.
What I meant was: the "we" in "we prefer" includes the original author.
If the uncompressed form is really unpractical to handle, it may happen
that even the original author prefers to get rid of it and keep a
compressed form for making further modifications.
In other words, when the uncompressed form is really huge, it may
happen that we fall back the case where the author deletes it, as
discussed above.

I hope it's clearer now.
