In theory you could set a bit in the dst entry and not use it next time
you connect to that host. That would be ok for web browsing at least
when creates new connections all the time.

But it's unclear how to even detect this situation reliably

e.g. you don't want to disable it just because there was a bit of
packet loss on a connection to a particular host earlier and there
is no clear heuristic to detect that this particular problem happened.

Agreed.
