correct. we could link to assembler code with _entry points and not worry about symbol
collisions in the rest of the code.

I'm pretty sure this dates back to PDP-11
days. I'm wondering "why?".
Why did the C compiler prepend an underscore to function names?
Sure was the PDP-11 :-) I vaguely recall that it was to make sure that
user functions did not conflict with predefined assembler functions, as
that would be a pain to diagnose (much like having swap overlap root).
