Would you elaborate on that please? I don't know what your situation is like that would cause rebasing to make spelunking harder.

> reverting a merge is possible but harder

Funny, someone else further down claimed reverting merges is easier. :)

Because you rewrote history it is harder to see what was written, tested by hand and tested with CI at what time.

Another social issue. In the projects i work with, it is commonly agreed upon and known that of course after a rebase every commit needs to be retested and reverified with CI. It is a bit of extra work, but as i mentioned in another commit: We do that extra bit of work now, to avoid having to analyze the cross-talk of a bunch of branch merges at a later point; mainly because that bit of later work often turns out to be considerably bigger. (Technical debt is a talking point here.)

Of course, this might be unviable when under unusual time pressures.
