Optional configure flag to flush history after each command?

[hugusmaximus]

Hello,

I understand the current history behavior is conservative for compatibility and historical performance reasons (which made sense in the 1990s with slower disks and different workloads).

However, would it be acceptable to add an optional ./configure flag (e.g. --enable-immediate-history-flush) that makes interactive shells append to $HISTFILE after each executed command?

Today this requires PROMPT_COMMAND="history -a". A compile-time opt-in would preserve defaults while allowing crash-resilient history persistence on modern systems.

Would this be considered?

Thanks.
