I don't like incompatible changes. The limit was introduced for a reason
(somebody got bitten). I would need a lot of convincing by a lot of
people before I'd feel that it could be changed.

What about these (they are just a few that I found with a quick grep):

|smtp_accept_max|Use: main|Type: integer|Default: 20|
|smtp_connect_backlog|Use: main|Type: integer|Default: 20|
|smtp_max_synprot_errors|Use: main|Type: integer|Default: 3|
|smtp_max_unknown_commands|Use: main|Type: integer|Default: 3|

You are right, though, that there is inconsistency. It's hard to be
consistent. In the case of queue_only_load, I think it might be hard to
pick a number that would be suitable for the huge variety of hardware
configurations that Exim runs on. Maybe. I'm no expert in exactly what
the load value means.
