Is your feature request related to a problem?

I want to reduce my connection limit on getting rate-limited.

A web server can decide to rate-limit number of connections out of the blue.

Describe the solution you'd like

Allow changing Session.connector.limit.

Describe alternatives you've considered

• Enforcing limit manually in a subclass.
• Changing Session.connector._limit.

Both can be avoided if the functionality is provided directly.
