It's not possible because nobody implemented it :)
From technical point of view I see no reason for it not
to be
possible, but on other hand, I believe that revisions, once you save
them were designed to be "untouchable" including all of their parts.
There is suppress feature that allows edit summary to be hidden from
regular users. I am not sure if "edit" summary feature wouldn't be
used by trolls or bad useres to alter old summaries in order to abuse
them for some sort of vandalism (if private data were inserted to old
revision summary there is high chance that it would be overlooked,
unlike in case of new revision)

Why isn't it possible to change MediaWiki edit summaries after posting?
I tried looking for it in Bugzilla; I expected to find a two-digit bug for
it, but I couldn't find any at all. Of course it's possible that I didn't
look well enough.
https://en.wikipedia.org/wiki/Help:Edit_summary just says that they can't
be changed, but doesn't link to a discussion.
So is there any reason not to do it?
