If I change insert-directory-program from one supports --dired to one
not, I can no longer open any directory in dired-mode. For example on
OSX, I have the `ls' from BSD and another one from GNU coreutils
installed as `gls', not to mention opening remote directories.
I think caching --dired switch in dired-use-ls-dired is a bad idea.

Not caching it is a worse idea.
There should simple be a note in the doc of insert-directory-program,
saying that if you change this, you may need to change
dired-use-ls-dired. If insert-directory-program were a defcustom
(currently, it is not even a user option), it could have a :set function
that makes the necessary change for you.

Could you elaborate on this point? I really would like to know.

I agree.

Just that it sounds very inefficient for everybody to have test what
options `ls' supports on every invocation, just because you are doing
something that sounds frankly rather odd.
There are many places in Emacs that test for features in external
commands the first time only, then make the IMO reasonable assumption
that the command isn't going to change underneath.
rmail-movemail-variant-in-use, find-exec-terminator, etc.
