When you use forwarding it doesnt cache the entry. ('forward only'
option in bind for example).

That's incorrect. Try configuring a forwarded zone and observe the TTLs
you get in responses. The "forward only" option disables recursion but
not cacheing.

I talked with Paul Vixie about doing this internal inside bind but that was
not something they would be delighted to do (at least not now). If you could
define how large your cache pool was for certain objects that would fix it

You might be able to hack it using a combination of forwarding zones,
views, max-cache-ttl, and attach-cache.
