Since this was addressed to me: I'm happy to answer questions with the caveat that I am not a military or a political expert. I'll also add that I have a long-running if recently less active AMA you can use for that to avoid derailing other threads. I don't check it every day but I do try to answer everything. This is the link to the AMA.

About the Hannibal directive: Yes, this is something discussed in the Israeli media. For those unfamiliar with the term, this is a command that was active for some years in the Israeli military intended to prevent soldiers from falling into enemy hands, which allowed forces to use a string of measures from roadblocks and creating obstacles, to using "all means" including firing in a way that potentially endangered the abducted soldier's life, in order to prevent their capture. While this directive was revoked in 2016, it was invoked in a handful of circumstances on Oct 7.
I know that at least at the beginning of the war, some commentators tried to use the existence of this directive to suggest that a significant proportion of the Israeli casualties on Oct 7 were from Israeli fire. This proposition does not appear to hold weight. 14 civilians are known to have died in this kind of circumstance on Oct 7 (out of over 800). 13 of them were in one incident, "Pessi's House" in kibbutz Be'eri, where a tank fired shells then troops entered a house in which 15 hostages were being held by some 40 militants, after an extremely long standoff. Only one hostage survived the ensuing firefight (one had already been killed before the incident). This event has been discussed in great detail in both the IDF investigation and journalistic investigations. The other incident was when a helicopter fired on a vehicle carrying Hamas militants and hostages, killing hostage Efrat Katz but freeing other hostages. I couldn't find numbers available for soldiers killed in friendly fire incidents on Oct 7 itself (as opposed to in the following war, where these incidents are reported clearly) but I doubt that the Hannibal command/approach caused a very high number of deaths among security forces, because there would be reported incidents at least through journalism if not through official channels.
So in order to answer your question: yes there is the will to look at it, but this has not been the focus of discussions about the failure of Oct 7 (other than very extensive discussions of the Pessi's house incident) probably because there are other much more urgent failings on Oct 7 and there doesn't seem to be a lot of evidence that this command greatly impacted Israeli casualties. I also wanted to footnote that while the Hannibal directive is shocking, it does need to be understood in the context of the hugely high prices Israel paid to redeem captured soldiers, including freeing over 1000 Palestinian prisoners to free just one Israeli soldier, Gilad Shalit, in 2011. Of those freed prisoners were many who went on to cause a lot of Israeli casualties, including Yahya Sinwar who masterminded the Oct 7 attacks. This is not an attempt to justify the doctrine but just to say that it needs to be understood in context.
