I noticed that over the past few months, future-proofing measures have been added to Save the Queen content (I.e. the Echo, and not having to remain on the buttons in CLL) to ensure players can still progress and earn their artifacts after Endwalker launches. However, I have not seen any such measures in Delubrum Reginae.

I am concerned that after Endwalker launches, it will be far more difficult to progress past that particular stage of artifact weapon progression, as Delubrum Reginae will be practically dead without 24 people wanting to run it at a time, especially given that the only other source of Timeworn Artifacts is Palace of the Dead, and AFAIK that source has not been buffed so it's still stupidly grindy. Furthermore, if a new player decides to do Save the Queen, DR will be a hard stop to progress (Meaning no access to Zadnor, the Dalriada, or Blade's weapons).

Will any future-proof measures be made for Delubrum Reginae, such as allowing undersized groups with the Echo?
