does the program not simply receive ^D as a normal character? I thought i was up to the program to interpret it

When a program reads from a pseudo-terminal device in "cooked mode"[0], ^D is the default control character to indicate "no more input will be made available."

A program reading from a file handle other than a pseudo-terminal or a pseudo-terminal set to be in "raw mode" will behave as you describe.

It does not. Its still up to the program with how it wants to deal with end of file though.

Yes but the expectation still is to interpret it as "end of input", even for interactive programs. One that doesn't (unfortunately) is zsh where ^D makes autosuggest prompt "do you wish to see all n possibilities?"
