I'm using bot=yes on some bigger, bot-like, edits often.

That would be good but on the other hand lots of very similar changes
should be grouped together in one changeset for convenience, if our
tools can't cope with it then let's fix the tools.  Otherwise you
might get 10k changesets in on run, each changing a single node, just
for the sake of not generating too big bboxes.

The ideal situation would be having infinite processing power etc. :)

But with the existing limitations, I think the "show bot edits" check
boxes is a fair approximation.  Frederik said it wouldn't be a
complete solution to the problem of easy monitoring changes in your
area, I think, because sometimes the bot edit is just the one you're
interested in.  But it is a nice feature if we don't claim that it's a
solution to this problem.  It would be a nice feature on its own.

On a different note, Frederik, you said you wouldn't put the "history"
tab on the website and didn't think it was a good thing.  Is that
precisely because of the bboxes problem (i.e. that the edit needs not
intersect the current view, just its bbox), or is there another reason
you said that?
