Some people are really against writable executable pages for security reasons. Eg. 20 years ago executable stacks were common, and people like OpenBSD and others made a stink about removing it. The W^X mitigations. More recently, Apple got really strongly into the "no executable writeable pages" stance, banning JITs from the app store and a bunch of other somewhat unreasonable stuff that is really about not letting apps download code without going through an Apple reviewer, rather than a practical security concern. Since that time there seem to be mildly dubious or cargo cult hate for writable code in some circles, who insist it's legit security practices and not a walled garden enforcement mechanism.
