While I think it should be possible in principle, this would turn out to be a large project, requiring building some new packages to be added to the repository. Can't make any promises right now, but I'll try to see if I can, if this is an important/necessary feature for you.
Thanks, it will be beneficial (especially increased security) for anyone using Emacs and doing something online with it I guess..
It might also be helpful to have the packages available for other programs.
That said, it is already quite nice to have Emacs 25.1 on its own. So no worries to drop the request if it appears to be too much work.
Emacs version 25.3 had an emergency fix that solved a security vulnerability.
Very unlikely anyone will be ever targeted on the N900 but if you use emacs to receive mail (like me) it is probably not a bad idea to add the following to your init file.
