There is no need to remember what was just typed.
There is a need to use commands that were typed a long time (years) ago.


Disasters often happen a long time after the backup (script/system) was
made.


The point is that you don't have to:
1. remember the commands
2. type the commands
3. correct typing mistakes


I know that I can save .ash_history
but it seems I can't load it without feature ENABLE_FEATURE_EDITING_SAVEHISTORY
set.


And convincing Arch Linux developers to turn on the
ENABLE_FEATURE_EDITING_SAVEHISTORY feature will be difficult. Because in
their initramfs environment they don't want to have a SAVEHISTORY to file
functionality.


I'm not convinced by this. Since your use case is a very rare one
(read-only "history" somehow defeats the purpose of the history - and it
overlaps what pre-written shell function is for). While I'm not one who can
make decisions on this, I'd suggest you just keep your local patch to do
this.
