What compression ratio would you recommend in order to a 4K DCP with no need of VFX?

4:1 is usually fine, and of course less is better. But I'd probably use VBR HQ for constant quality.

If we shoot CinemaDNG lossless, how many minutes length we can expect as average going with VBR HQ for archive @ post?

If we shoot lossy 4:1 CinemaDNG, would there be any chance to still save space in disk without losing 4K DCP output in mind? If so, what slimraw route?

It depends; variable bit rate means size will vary with image complexity. It is usually (but not always) between 3:1 and 4:1, might be around 600GB for a couple of hours of 4K.

I wouldn't bother shrinking a 4:1 source any further, but if you really have the inclination, you can try 5:1 or 7:1 on top of it, which will shave off ~20% and ~40% respectively. Ofc, always test and judge results yourself.

3.1 is (was) 64m /500GB (4K Dci 24p)...2 hours pre-braw on 500GB has never been a possibility in 4K

In an interview with Cinema 5d IBC 2018 Blackmagic said we are interested to provide BRAW for other camera manufacturers too! That too for free!

I would love to see BRAW in Fujifilm x series with/without monitor! But I want SDI output from Fujifilm x cameras! 

Recently they anounced 12g sdi RAW output with blackmagic video assist! Who knows blackmagic would become new atomos!?
