The whole benefit of the Chase UR ecosystem is not having to commit your points to a specific program until you are ready to redeem.

Unless there is a transfer bonus, making a speculative transfer to any specific program can leave you with orphan miles and it also removes the flexibility to redeem them elsewhere if something else arises (e.g., transfer to Hyatt and then suddenly LH F is available for your dates on UA or AC and you no longer have UR to transfer for the booking -- yes you haven't wanted to use for airlines in the past but the point is you lose that option completely if you commit them over to Hyatt).

Given the longstanding ties between Hyatt and Chase (think co-branded card), no reason to think that option will disappear. Of course if you have a redemption in mind to make after you transfer, that's a different story, but for hypotheticals you are better off keeping the flexibility of UR.
