Still, the Tasm tool does it on purpose. It has choice, it just decides
oterwise. When dealing with COM files, there is no choice.

The design of the COM-style loading led to simplistic stack
sizing and allocation. I doubt COM loading was designed with the
specific goal of allocating a full 64K of memory with stack at the end -
it was just a consequence of an earlier design choice.

In the case of EXE files, there are headers to deal with this
situation. A tool that sets the headers in a specific way does so on
purpose.
