I recall that discussion at the time, and the thread continued
http://www.riscos.info/pipermail/rpcemu/2011-October/001384.html
then fell silent.

The tests performed in the post you've highlighted didn't really elicit any
new information:
Old FileSwitch + 4GB files + vanilla HostFS => doesn't work
Old FileSwitch + 4GB files + 4GB HostFS => doesn't work
New FileSwitch + 4GB files + vanilla HostFS => doesn't work
New FileSwitch + 4GB files + 4GB HostFS => does work

the point being that having the underlying HostFS being 4GB capable is
harmless for OS versions that it already doesn't work on, it's only when
coupled with RISC OS 5.20 and (chronologically) later that you get benefit.

RISC OS 3/4/6 don't handle > 2G files gracefully out of the tin, and nor do
they with an updated HostFS.

Patch attached for 0.8.14 for reference,
Sprow.
