Makes sense, I like it, thanks for elaborating. [ Especially that you 
used "(no) flatten" phrasing, where original `--preserve-merges` 
documentation says it`s used "not to flatten the history", nice touch ;) ]

Not sure if I would prefer original `recreate` instead of `remerge` 
as that particular strategy name, though, but might be I`m just more 
used to the former one at the moment.

But if I think about it more, "recreate" seems straightforward enough - 
create something (again), kind of making it more obvious that it is a 
new thing (that we are now creating, again, based on some old thing).

On the other hand, "remerge" communicates "merge something again", 
which doesn`t necessarily mean creating a new thing (based on, but 
not attached to old thing), and could also be interpreted as "merge 
existing thing again" (and leaves me wondering if it would better 
suite some other strategy possible in the future).

Not sure if that explanation suffices, but it comes to "recreate a 
merge" having more clear meaning than "remerge a merge", being 
somewhat ambiguous, thus confusing (to me, at least).

I don`t know, thinking too much?

Regards, Buga
