Because we are unable to allocate address space without also allocating memory, even unused portions of the compressed heap make less memory available to all other allocators in the process. The memory savings in the compressed heap will only out-weight the lost memory for other allocations if nearly all of the application's memory usage is in Dart, rather than, say, graphics or plugins.
