Daemons aren't Multiverse-devouring horrors that are waging a cosmic war on every universe simultaneously, so no.
So some idiot on some Hive-World in the 40k galaxy reads from pic related and unleashes the Deadites upon the galaxy...

They more or less do tho?

Only if you take the current state of the lore, End Times, and Age of Smegma as canon. Othewise, no.

At what distance?
Because as soon as that spreads beyond the first planet, everything is getting nuked. Really, there's not that big of a difference between this and the Plague of Unbelief or Plague Zombies.
They will get exterminatus'd, and it'll crop up in this or that sector every once in a while, with the odd planet infected, a ship here, a ship there, that slips through the blockades.
But it's unlikely to be an overwhelming issue, all things considered.

>I don't think timeline-jumping cosmic horrors that can infect and damn your soul with but the slightest touch are "bog standard" in 40k
You pretty much just described daemons and Chaos in 40k. That's pretty much exactly what they are. You couldn't have nailed it better if you'd tried.

The problem with Chaos is that it is not unified. At all. The forces of Chaos will fight amongst themselves just as much as they will fight against anyone else, purposefully sabotaging themselves in order to gain advantages over each other. That is the primary reason as to why they can hardly get shit odne, and start taking over the galaxy in full. The Deadites on the other hand, -are- unified. They are an utterly colossal Hive-Mind working in tandem in order to subsume the multiverse, and are only held back because Ash, the "Chosen One", is a universal constant within every reality.

No, actually, it's the other way around. It's the newer lore that reduces daemons to mindless warfare that exists within the temporal limitations of the ongoing timeline. Canonically, The Warp/Aethyr literally has no concept of time at it's core, and every touch by a daemon can quite literally corrupt you, and practically all daemons can possess you, especially if they have not taken corporeal form (it is, in fact, the only way they can exist in realspace/the materium for extended periods of time).
It's the End Times/Age of Smegmar that upsets this, with a physical Slaanesh physically trying to enter the real world, and lots of games with daemons popping out of nowhere, and so on and so forth. Going by established canon and the nature of daemons, that shit shouldn't happen - the very idea of some kind of standing daemon army is ridiculous; they'd need to be anchored, whether they're greater daemons or not. They usually do this by actually possessing someone and warping their body as they see fit.
"Timeline-jumping cosmic horrors" sums up the Chaos Gods almost perfectly, prior to the new canon that have reduced them to actual individuals defined by the boundaries of human understanding, with daemons just popping out of the blue and fighting regular warfare.
Canonically, a human army in, for example, Warhammer Fantasy, would be absolutely fucked by any kind of daemonic standing army. Khorne used to give his champions bolters, for fucks sake.

All more or less true, but a different point entirely.

No. You idiot. This has been happening since before Veeky Forums was a twinkle in moot's testicle.
This has been happening since before 40k.
This has been happening since before the earliest stories were written down.
