At 31:17, I like how this video shows the bolt hold open on the last round, and then bolt close button being used after reload. (although a lot of modern SMG have this)

I never understood why MP5 was designed to rack the bolt open first before reloading, and no one change this design when cloning it.

Stumble on this cs/LS7

Google says bolt hold open was not widespread yet by the time it was made. Besides the AR & pistols, I'm not sure I can think on top of my head any other firearm that has that feature at that time period.

You are correct.
I think I should clarify what I meant. For MP5, you can't plug in the magazine when the bolt is closed (I remember you technically can, but it won't guarantee the round would chamber when you slap that bolt close). You have to rack it open before plugging the magazine in.

Bolt hold open actually already present on M1 Garand, M-14, MAS-49, Gewehr 43, SKS and EM-2. Its just German and Soviet small arms decided to discard bolt hold open for their post war weapons.

Oh yeah, I would love someone to help translate that video in your message.
