I don't think it is stupid.

You can't.

I could imagine adding a separate function or some option to
curl_easy_getinfo() that could get that ability. Or perhaps it would be even
better to add a separate function to use for querying the library during
operations (as curl_easy_getinfo() is otherwise only to be used after
transfers are done).

The problem is that we don't necessary know the size and we can't really tell
when we'll know it. Theoretically, from a very slow or loaded server sending
lots of headers, we could wait a long time for the length to get known and
the write function can be called numerous times before that.

Consider it an information I thought mostly was interestin for progress
information,

Adding a progress function is a very minor thing, and if you pass a struct
you define you could set it as soon as the information is there and then your
program would get to know...

Of course I need people's views on this!
