Yes, indeed, this is very annoying.  There are many other local variables
(including numbers!) for which Emacs asks this question.  Look, for example,
at this section:

## Local_Variables:
## perl-indent-level: 2
## perl-continued-statement-offset: 2
## perl-continued-brace-offset: 0
## perl-brace-offset: 0
## perl-brace-imaginary-offset: 0
## perl-label-offset: -2
## cperl-indent-level: 2
## cperl-brace-offset: 0
## cperl-continued-brace-offset: 0
## cperl-label-offset: -2
## cperl-extra-newline-before-brace: t
## cperl-merge-trailing-else: nil
## cperl-continued-statement-offset: 2

It seems all these variables are safe, isn't?

Perhaps Emacs shouldn't be released without marking all safe variables in
packages distributed with Emacs.
