Projection action with binary result larger than 64000 bytes

I recently created a simple action:

1action GetResult Binary {
2   initialcheck none;
3   parameter ResultId Integer;
4}

This action will simply return a BLOB with roughly 200 kilobytes.

When I try to call this, I get the following exception back:

I understand that we shouldn’t return large objects from a single HTTP REST API, but 200k isn’t an extreme case. Why even implement binary as a return type if it’s restricted to 64000 bytes?

Or maybe I’m just missing something?
