It does like more RAM than FFS, but can be tuned to work under
smaller amounts however given current pricing does anyone use HW for
servers with that little RAM?
Sure old i386 machines still running legacy ABC that just works so
no need to upgrade it may still have less than 4GB RAM, but modern
machines running large disk sets are a totally different matter.

Not experienced that here, care to clarify / quantify?
While if this is the case I can see that may cause problems, but the
solution to that is simple don't let your system get that full.
Disks are still relatively cheap even after the disasters, so keep on
top of your space and you wont see that problem; particularly as ZFS
makes it so easy to expand existing pools :)
