Locale/Encoding changes are not part of the inside of the database at all
so there's no guarantees for that.  For the others, sometimes people do
work on textual representations of dumps. Neither of those is a reason not
to have an option to turn them off in restore, but the check should be
allowed if desired.

If you look at the -hackers discussion, options for this were talked
about recently, but it came pretty late in the 7.4 development cycle,
after beta started. It might happen for 7.5 if a consensus is reached for
behavior.
