It would seem worthwhile to try to get the transcripts into the public domain before the expiry date.
Sorry, I think I was unclear. Transcripts are an exception to the usual rule of immediate online availability. The court reporters, who are in part compensated through the sale of transcripts, get a 90-day exclusive window. During that time, transcripts must be purchased directly from the court reporter and tend to be pricey. After 90 days, the transcripts may be purchased on PACER like any other document (except that the .10/page cost isn't capped at $3.00 like other filings.) Once on PACER, they remain available indefinitely, and may be purchased at any time.
