Comment(by azaozz):

 Many users copy and paste content from web pages and that usually inserts
 a number of html tags and styling without them realizing it (depending on
 the browser). Since the <iframe> has some security risks, better to enable
 it only for users that require it (via a plugin).

 Also <iframe> is invalid in both HTML 4.1 Strict and XHTML 1.0 Strict and
 many themes use the strict DTD.

 We can match the restrictions from kses in `invalid_elements` for non-
 admin users, although it would probably bring some "the editor mangles my
 code" complains.
