No, but that somehow there should be one cache per used value of KDEDIRS.
Since putting the value of KDEDIRS into the name of the file might lead to
something awfully long, maybe there could be something like a ksycocarc with
[/opt/kde3]
FileName=ksycoca1
[/devel/kde/inst/kofficedir:/devel/kde/inst/kde3]   # my value of KDEDIRS
FileName=ksycoca2
[...]
etc.

This way, for a given value of KDEDIRS, the code can easily lookup the ksycoca to
use, and two sessions of KDE with different parameters will stop overwriting
each other's ksycoca. Am I missing anything?

That's another solution, but it leads to all sorts of updating problems (where
installing a binary package, as administrator, must run a command that updates
the system-wide ksycoca)...
