clarify implications of disabling SignalR MaximumReceiveMessageSize

[cyungmann]

Description

This page says that

Increasing the value might increase the risk of Denial of service (DoS) attacks.

Under what conditions does or doesn't it increase the risk of Denial of Service (DoS) attacks? Is this risk mitigated at all by using an AuthenticationScheme on the SignalR hub requiring bearer access tokens in the HTTP headers (i.e. does this prevent unauthorized users from performing DoS attacks)? Are there other implications (security, performance, etc) of increasing the value or disabling the limit entirely?

See also my SO question about this here.
