One problem with the current policy (requesting all automated editing processes to use `maxlag=5`) is that this creates a binary threshold: either the query service lag is under the threshold, in which case bots will edit at full speed, or the query service lag is above the threshold, in which case they should all stop editing entirely. This is likely to create an oscillating behaviour, where all bots start and stop periodically. This is probably not ideal neither for the infrastructure nor for the users. Not all automated edits are long-running tasks where stopping for an hour is acceptable: many QuickStatements or OpenRefine batches are under 10 edits for instance. As a user of these tools, I would expect them to slow down when lag is high, but stopping entirely should be extremely rare, as it breaks workflows. I think it would be preferable to get a continuous throttling behaviour: the higher the lag, the slower the edits. This can already be achieved by clients by using a small maxlag parameter and increasing it gradually as they retry. For instance, start with maxlag=2, which fails, retry in 1 sec with maxlag=3, which fails, retry in 4 seconds with maxlag=4, which fails, retry in 8 seconds with maxlag=5, which fails, retry in 16 seconds with maxlag=6, which succeeds. Would such a behaviour be acceptable?
