Here is the reply (per Trevor Darnell) if you receive this question:
“At this time, we have no plans to increase the character limit because it is meant to be a smaller amount of text by program design. We want to encourage shorter CQI cycles with more targeted goal-setting (fewer goals per CQIP and, thus, shorter action plans per CQIP). You are not required to include so much information unless this is a LWDB-imposed requirement. I hope this helps.”
