I noticed the same exact things during the stream!
There are bound to be a few restrictions in the game that won't give us freedom like traditional D&D will, but Larian have done an excellent job with the GM mode so far. I can't see why the suggestions you made wouldn't be considered.
I'm particularly interested in NPC's following the party. Let's say I'm no fighter- so I dump all my points into charisma & try to convince the people I meet in my travels to fight for me. It would be a hassle for the GM to control my NPC army. It would be a lot easier for them to simply have a follow command. This allows for more creativity/freedom.
It's a neat idea, but diplomatic coercion doesn't work that way - You can convince someone to aid you, yes - but the checks required to coerce them into performing dangerous aid, or lengthy aid increase the DC so much that it would be nigh untouchable unless the NPC had a positive attitude toward you.
And Intimidation doesn't allow you to force someone to do something dangerous against their will at all.
Though, this is all subject to what the GM will allow, of course, and also varies depending on the rule set you're using.
