you need to do a search&replace that goes beyond the dumb thing that the
dialog offers, well, bad luck.

What do you do to search&replace in all files across the project?

What I do is invoke a searcher such as "ag" or vc-git-grep and then
wgrep to operate on the resulting buffer. This has the advantage that I
can simply do a replace-string or a more detailed manual edition on a
case-by-case basis with the associated file on a side window for
context, etc.

A lot of the time, you don't need detailed editing for matches, though.

And the "dumb thing" the popular editors offer serves this case (as well as many others) actually very well and better than Emacs. So there's no reason to feel all smug and content, in my opinion.
