There was a strong argument for increasing the 3 month order window during Covid and for the first year or two afterwards, as lead times were, in many cases, were much longer than that. However, the overwhelming majority of these issues are now resolved, so there is far less of an arguement for it now.
Also, as can be seen from this forum, quite a few people change their minds between ordering and delivery (for a multitude of reasons, not least AP changes), so the wider the order window the bigger the issue that this becomes!
