Doesn't sound like good reasons to me, sorry.  I'm guessing this
variable was made a defcustom under pressure from people who didn't
want to see "(DOS)".  Me, I just modified the indicator to be just a
single backslash.

You are shooting yourself in the foot if you set this globally.  Of
course, Emacs users should be free to do that, as part of their
freedom, but we don't need to bother "fixing" such use cases by
binding the variable in every place where its being non-nil could
break standard features.
