Thanks for this clear answer, John!
The MEX question is solved for me with that.

I do not think, that animated or transparent GIFs have been dangerous ever.
It was the TMWs (your) decision to dare to open a platform for publishing at least potentially dangerous M-functions (!) and this is really and totally helpful! 

I'm happy, that even TWM cannot read in P-coded files.

I'm wondering what "essentially defunct FEX team" means. I'm convinced that the remainding(?) team can encourage somebody from the WWW team to rectify the page for new submissions and the guidelines.

Kind regards, Jan
