Yes that makes sense. You don't want to run arbitrary commands that you
are not aware of because those are set by the modeline.

Because this is not potentially run when reading the file. The user will
need to run this manually and hopefully he knows what he is doing.

Define a custom command so you don't have to type it manually.

I hope this is not possibly and I won't support such a thing for
security reasons.

Better hope you get what you want before you stop wanting it.
