Is it only me or is the ZFS memory usage for desktop computers uncomfortable?

Dear NetBSD users list,

I understand that on a server, often it's worth sinking a lot of memory 
into ZFS for better performance.

But is it only me, or is this trade-off not the same for desktops?

50% of memory less may have severe consequences on a desktop:

- Many modern games that would maybe have worked via wine or a VM, will 
no longer work since e.g. many will work with 16GB but not with 8GB.

- Some audio software similarly may require a lot of memory to run.

- Compiling many rust projects or some C++ projects will require more 
than 8GB RAM, it would work on a 16GB RAM machine but not with ZFS.

I was surprised to see that this memory usage is configurable for many 
ZFS implementations, but apparently not for NetBSD's:

https://wiki.netbsd.org/zfs/#index5h1

Are there any plans to change this and make it configurable? Perhaps 
without recompiling the kernel, too?

I've already told one person to better not use ZFS on a desktop. I would 
love to actually be able to recommend it.

(I also heard people worry ZFS means LLM code. I wonder, does NetBSD's 
ZFS upstream include LLM code? What's the outlook of that once new code 
is pulled in? Or is NetBSD's ZFS just its own independent fork now?)

Regards,

Ellie
