Shall we support DMG dowload from an EPUB?

[gautierchomel]

for The pub-foreign_bad-fallback test results in the DMG file beeing proposed to dowload by Thorium (Explorer window opens to select a place to save the DMG).

This makes the test N/A because we support DMG but is this good for user?

On another point of view an EPUB could include a DMG (or EXE or whatever) that user could download thru a concrete action (activating a link a link). I know no use case but why not, as an example an Author could propose a progam included in his technical book.

We prefer not supporting because it is a possible security issue for the user.
