The flag is set by functions that are about to insert, delete, or
replace portions of a buffer.

IMNSHO, this doesn't make sense. E.g., what if the buffer is very
large, and there won't be enough memory to have another copy of it?
Even if it is not that large, why move large amounts of data in this
case?
Emacs uses the gap buffer paradigm precisely to avoid this kind of
lossage. It doesn't make sense to throw that out the window for the
benefit of a minor improvement.
