I hope I'm wrong, but isn't this at the cost of admins
working with long rules' sets, which (probably) take extra
time now?

That's right, it makes the insert and delete operation more
expensive.

A compromise would be to delay the flushing and wait for
some time (default 2 seconds) whether more rules or routes
are being added before flushing.

Another idea Thomas and I tossed around was to have some kind of way
for the rule insertion to indicate that the flush should be deferred
and I kind of prefer that explicitness.

By default it's better the flush immediately, because the old
behavior is totally unexpected.  "I insert a rule and it dosn't
show up?", nobody expects that.
