So this topic is very underwhelming and not power(strength) related at all, but it needs to be brought up..
Saul created this beautiful Library where he salvaged all the Ohara Books and when a Book enters the door it's size transform to that of
a readable book for Giants.. At first glance, whatever the source of it's power, it's very convenient to have bigger books to pass on the Ohara knowledge to other Giants and Saul himself allowing him to read them.. Although aside from the Library assistant Ange, i'm not very convinced that Saul and the other Giants are much interested in those scriptures or their content, there's no reason why this Library couldn't have been a Dollhouse like the Strawhats were trapped in.. I suppose it's more majestic like Elbaf's village, as the explorer Louis Arnot said, '' To be in the presence of Gargantuan is to know emotion '', hence hitting more home with Robin..
Saul had 20 whole years to build this book haven, and it took maybe 1 year max 2 years to construct the shelter.. The process was incredibly accelerated by that special portal at the entrance.. It almost feel like a missed opportunity to not have Saul dedicate a part of his life to transcribe those books himself by hand into Giant handmade crafted Books to deepen his endeavor and rescue mission of the books that the oharians gave their life to save from flames.. I'm idealizing this way too much..
What i'm suggesting is that '' power at the door '' will serve another purpose, it's true intended one by the author at the end of Elbaf..
Recalling again sir Louis Arnot, he mentioned this..
If the Strawhats remain too long in Elbaf, they will literally.. Grow.. If regular beings stay too long in Elbaf, they start to increase in volume.. I'm not saying the Strawhats will all become Giants, but i can envision them reaching the size of the Elbaf Kids or as tall as Admirals..
So when it's time for the Strawhats to leave this arc, there will be an ability that can circumvent this condition and use that '' Power at the door ''.. Assuming that Giant Books can go back to normal scale when going in the other direction..
Either Mont D'or(Big Mom) will show up and become an ally for the Strawhats to be put in Books to take advantage of the portal and be
Downsized, or an ability user that can cleverly tweak the rule of book transformation such as being turned into paper, or even better that
power is a devil fruit user and is not limited to magnifying Books.. I'm sure if it's the case, there are imaginative possibilities for the Strawhats to be reduced back to average human lenght..
Anyway that's it..
