Trac recognizing duplicate bugs on bug submission

Can we atleast try this to see how it works? I can't remember but do you
guys have a machine for these sorts of things?

For example, for 2.7.0 there were 86 duplicate tickets:

2.7.1, there were 25 duplicate tickets:

For 2.7.1 it seemed like it was released a few weeks after 2.7.0, hence the
less number of tickets. Between 2.6.x and 2.7.0 it was basically 3 months.
86 tickets may not seem like a lot, but I think this plugin would come in
handy if, for example, there is a flood of emails/tickets for the windows32
installer <>.

Anyways, I think it's a good idea. I'm not sure if someone has time to
devote to install this plugin for trac. I can help if help is needed.
