Some people are working on packages support, but it probably will not be ready in the near future

This is indeed a problem. In practice, it's unlikely that this will be possible because there is no grand vision or overarching plan of how the RTL should be. It is developed on an ad hoc basis, and e.g. compiler-specific helpers are added/removed/renamed as the compiler itself changes.

So programs compiled by a particular FPC release will probably only ever be guaranteed to work with the "BPL" compiled from that same release. They will have to be versioned just like any other library.
